Introduction: The Development Agency Scaling Problem Every dev agency dreams of scaling smoothly. But rapid growth isn't just about landing new clients or hiring more devs; scaling pains often surface as project delays, burned-out teams, and annoyed clients. Traditional project structures, with their confusing hierarchies and waterfall planning, can't keep pace in today's agile world. We asked ourselves: How could we deliver value faster, maintain code quality, and keep our developers happy? All while tackling complex, overlapping projects with shifting requirements? The answer: Rethink everything. By adopting the Spotify Model and retooling our processes (with a massive assist from platforms like Teamcamp), we saw an 89% increase in velocity without sacrificing quality or sanity.

ChatGPT is powerful, but most people don’t get great results. I’ve seen these same mistakes repeated by students, entrepreneurs, and even executives. After writing 40+ AI books and helping businesses adopt AI, here are the top 5 mistakes — and what to do instead. 1️⃣ Being Too Vague Vague: “Write a business plan for me.” Precise: “You are a startup consultant. Write a business plan for a subscription-based fitness app targeting working professionals. Include pricing, marketing, and growth strategies.” Fix: Always add role, context, task, and constraints. 2️⃣ Expecting a Perfect Answer in One Shot AI works best in iterations, not one-and-done commands. Vague: “Write me a LinkedIn post.” Precise: “Write me 5 LinkedIn post ideas about AI in business. Then expand idea #2 into a 200-word draft…  ( 6 min )

By Frank, Senior Electronics Engineer, USA When it comes to designing printed circuit boards, the stackup - the way the different layers of copper and insulation are arranged, is crucial. Moving from a basic 2-layer board to a 4-layer design offers significant benefits in signal integrity, noise reduction, and power stability. Drawing from my years of experience, I want to share practical insights about 4-layer PCB stackups that can help you achieve reliable, high-performing designs. In simple terms, a 4-layer PCB sandwiches two signal layers on the outside with internal layers dedicated to power and ground. This arrangement helps control electromagnetic interference much better than a 2-layer board and provides solid reference planes for signals to return to, which is essential for smooth…  ( 7 min )

Transaction Fee Transaction fee = Gas units * Gas price Gas units: unit of computation for executing an operation. Gas price: how much ETH you pay for every gas unit, it is composed of base fee and priority fee (tip). Gas limit: the maximum gas you allow for one transaction. Gas refund: unused gas will be refunded to sender after the transaction finish. Out of Gas: if gasUsed > gasLimit, transaction will fail and rollback all state changes, but the gas already used will not be refunded. Batching: better to split heavy computation into multiple smaller transactions to avoid exceeding gas limit. // ❌ Bad: // function doMassiveLoop() public { // for (uint i = 0; i < 1000000; i++) { // // ... do work // } // } // ✅ Good: batches uint public start = 0; uint public constant INCREMENT = 100; function doWorkInBatches() public { uint end = start + INCREMENT; for (uint i = start; i < end; i++) { // ... only do small part of work } start = end; // update next starting index }  ( 5 min )

Day 72 was a mess, but a productive one, I guess. It started with a solid night's sleep, which is rare these days. The goal is to keep my work consistent, and that's been going pretty well. Workouts, on the other hand, are another story. It's a constant battle, but I’m determined to win. I’ll be back at it tomorrow and hopefully for a few more days after that. My side project, Mutiny, is a constant presence in my thoughts. I spent a good chunk of my evening stressing over how to increase engagement on our project posts. It’s a core part of what I do, and getting people to notice it feels like the next big hurdle. Last night, I found myself in a different kind of mental gymnastics: figuring out which class I could afford to miss without my attendance dropping below the dreaded 75% mark. It's a weird kind of strategic planning that every student who's also a builder knows all too well. This morning was all about college prep. I was deep into OCaml for a quiz on Monday and exams next week. Just finished my revision of Python libraries, and tomorrow I’ll be moving on to linear and ridge regression.

How to serve web content on the internet using public IPs. The Challenges I faced. One of the main challenges I encountered was getting the correct command syntax while setting up the Apache web server. I kept making small mistakes — like missing sudo, using the wrong file paths, or incorrect echo/tee syntax. Every time I tried and failed, I learned a bit more about how Linux commands work. It was frustrating at times, but I didn’t give up. Instead, I double-checked documentation, retried with corrections, and gradually figured out what worked. That process — of failing, adjusting, and trying again — is called persistence, and it’s a crucial part of learning anything new in tech.

Databases are the backbone of most applications, but as they grow, performance can take a hit. Imagine a massive User table stuffed with profile details, login history, and billing information. Queries slow down as the database scans irrelevant columns for every request. Sound familiar? Let’s explore vertical partitioning—a powerful technique to streamline your database—and touch on caching for even faster data retrieval. What Is Vertical Partitioning? Vertical partitioning splits a wide table into smaller, focused tables based on usage patterns. Instead of one bloated User table, you create separate tables for specific data groups. This reduces the number of columns scanned during queries, boosting performance and minimizing disk I/O. Profile details: name, email, profile picture As the t…  ( 6 min )

However, when it comes to constructing request payloads—especially for APIs with strict schemas like GraphQL—the spread operator can become a dangerous tool that introduces runtime errors and security vulnerabilities. Consider this common pattern when building API request payloads: // ❌ Dangerous: Using spread operator for payload construction const createUserPayload = { ...userFormData, // Contains: name, email, age, debugInfo, internalFlags ...additionalData, // Contains: preferences, metadata, tempId ...feature…  ( 9 min )

The way that mobile applications are constructed these days is considerably different from a decade ago. Users today no longer only anticipate natural but also trendy, personalized, and consistent user experiences across devices. These expectations call for diverse sets of features, multiple form factors, diminishing cycle times, and the requirement for frictionless scalability. Traditional development patterns — static, monolithic codebases—are frequently not able to keep up. Introducing a new feature can be like doing surgery on a runaway train: risky, time-consuming, and likely to have side effects. Composable Architecture swoops in as the game-changer, offering the chance to build mobile applications that are flexible, testable, and modular from day one. Rather than viewing the applica…  ( 7 min )

Tchaca is a junior dev who just entered the React world. On a normal workday, she faced a question: “I need to manage some state in my component… but should I use useState or useReducer?” This is a super common question - even experienced devs get confused sometimes. Let’s follow Tchaca’s journey and understand when to use each one, with simple day-to-day analogies. When to use useState useState is like a sticky note: you write something simple, stick it on the screen, and whenever you need, you can update what’s written there. It’s perfect for small and straightforward things, like: const [darkMode, setDarkMode] = useState(false); return ( setDarkMode(prev => !prev)}> Mode {darkMode ? 'Dark' : 'Light'} ); 👉 Why useState? It’s jus…  ( 9 min )

When writing Java programs, you’ll often need to choose between two values depending on whether a condition is true or false. Normally, you might use an if-else statement for this, but Java also gives us a more concise way: the conditional operator, also known as the ternary operator (?:). The General Form: condition ? valueIfTrue : valueIfFalse Java checks the condition, which must evaluate to either true or false. If the condition is true, the whole expression evaluates to valueIfTrue. If the condition is false, the whole expression evaluates to valueIfFalse. This allows you to write decisions in a single line of code. int x = 5, y = 10; int min = (x < y) ? x : y; System.out.println(min); This evaluates to the same result as writing; int min; if (x < y) { min = x; } else { min = y; } Final Thoughts The conditional operator is a handy shortcut that can make your Java code more elegant. For quick decisions between two values, it’s often better than writing out a full if-else block. Next time you need to choose between two options, try using ?: and see how much cleaner your code looks!  ( 6 min )

Preface In Solidity, there are two kinds of arrays: Fixed-size array: You must specify array length at declaration time. Example: uint[5] numbers; Once created, the length is not possible to change. Dynamic-size array: No need to specify length at declaration. Example: uint[] numbers; The length can be changed at runtime (grow or shrink). Most common syntax uint[5] numbers; // fixed size array uint[] numbers; // dynamic array numbers[i]; // access by index uint[] storage refToNumbers = numbers; // storage reference function f(uint[] memory a) external { ... } // pass memory array numbers.push(x); // append to end numbers.pop(); // remove the last element uint n = numbers.length; // get length delete numbers[i]; // reset value to default for (uint i = 0; i < numbers.length; i++) { ... } // loop When declaring an array inside a function, you must use the memory keyword. A memory array always have fixed size, so you cannot call push or pop. You can use the new keyword to create a memory array based on a variable size. Example: function createMemoryArray(uint size) public pure returns (uint[] memory) { uint[] memory newArr = new uint[](size); return newArr; }  ( 5 min )

Você já percebeu que algumas funções “lembram” valores mesmo depois que o componente re-renderiza? Isso acontece por causa de closures. Em JavaScript, uma closure é quando uma função consegue acessar variáveis do escopo onde foi criada, mesmo depois desse escopo ter sido executado. Exemplo simples em JS puro: function contador() { let count = 0; return function() { count++; return count; }; } const incrementar = contador(); console.log(incrementar()); // 1 console.log(incrementar()); // 2 console.log(incrementar()); // 3 A função incrementar mantém acesso à variável count, mesmo depois que contador() já terminou de executar. Isso é uma closure em ação. O problema no React Ao digitar num input e disparar uma busca a cada tecla, sua API sofre. Queremos esperar o usuário parar…  ( 6 min )

Implementing push notifications on Android or iOS is rarely straightforward. On iOS, you’ve got APN certificates to generate and renew. On Android, you’re dealing with Firebase server keys. And then there’s the fun part figuring out why your notification never arrived, even though nothing looks obviously broken. These failures are often silent, and the logging you get isn’t always helpful. Most apps rely on push notifications for engagement: reminders, updates, alerts. But the tooling around them? Honestly, it’s more complex than it needs to be. Between platform differences, cryptic error messages, and all the moving parts in the setup, it becomes a pretty heavy lift for mobile developers. This is where Clix.so, a notification platform built for developers, plays the part. This platform r…  ( 10 min )

When developing your frontend application, most of the time you work with the data coming from or sending it somewhere.

What is AGENTS.md and Why Should You Care? Vladislav Guzey ・ Aug 21 #ai #programming #tooling #productivity  ( 5 min )

If you’re like me and work with multiple AI coding agents, you know the frustration of managing different instruction files. It’s a pain to keep everything updated across various formats. But I’ve got some great news for you. A new, simplified standard has emerged, and it’s called AGENTS.md. For a while now, working with different AI agents meant juggling multiple configuration files. Whether it was claude.md, gemini.md, or .cursor/rules, each agent had its own format. This created a mess of redundant files that all needed to be updated separately. It was inefficient and confusing. Big companies recognized this problem. They came together to create a unified solution — AGENTS.md. The goal was to establish a single, predictable place for all AI agents to find the instructions they need to …  ( 7 min )

When web projects outgrow the comfort zone of a single server, developers often face a familiar chain of problems: downtime during deployment, inconsistent environments, unpredictable traffic spikes, and complex scaling decisions. Traditionally, teams relied on manual server configurations or fragile scripts to keep applications alive. In a classic setup, hosting an application meant provisioning a server (or a VM), installing dependencies, and hoping that the CPU and memory would hold up under load. Scaling usually meant either moving to a larger server (vertical scaling) or setting up additional ones (horizontal scaling), often managed by hand. Kubernetes to the Rescue Kubernetes (K8s) is an open-source architecture system designed exactly for these pain points. Instead of treating serve…  ( 7 min )

In my previous blog, we explored how to verify file integrity during transfers using SHA-256 checksums. So how do we make it tamper-proof and also be able to verify authenticity without jumping to heavy public key cryptography? HMAC stands for Hash-based Message Authentication Code. You take your file (or message), Combine it with a secret key that is known only to sender and receiver Run it through a hashing algorithm like SHA-256. The result is a hash that can only be reproduced if you have both the exact file and the shared secret key. Why this matters: Generate HMAC-SHA256 hash of the file using the shared secret key. Send both the file and the generated HMAC hash. Recompute HMAC-SHA256 hash of the received file using the same key. Compare it with the sent hash. Match ✅ → file is intac…  ( 7 min )

One of the most powerful exercises in the ALX Software Engineering Program is creating a vision board — a snapshot of who we want to become in the near future. When I look at my vision board, I see more than just pictures. I see a commitment: A laptop filled with code reminds me that I will grow into a confident front-end developer. A smiling remote worker represents the balance I aim to achieve — building a career while maintaining personal well-being. A group of people symbolizes collaboration with my peers, because growth at ALX is never just personal, it’s shared. A certificate stands for recognition, celebrating the wins both big and small. The beach scene shows my dream of flexibility — working from anywhere in the world. And finally, the growth icons remind me to keep learning, keep evolving, and keep contributing. This vision board is not only about where I want to be in 4 months, but also who I am becoming every day. With the support of ALX and my peers, I know this journey will be both challenging and rewarding.  ( 5 min )

The Waterfall Model in software engineering is one of the earliest approaches to software development. It follows a strict linear sequence where each stage must be completed before moving to the next. While it is simple and well-structured, it also has several limitations that modern methodologies attempt to solve. The Waterfall Model is a sequential software development process. It was first introduced in 1970 by Dr. Winston Royce. The model is called "waterfall" because progress flows in one direction, similar to a waterfall, without going back to previous phases. The development life cycle under this model usually includes: Requirement Analysis – Collecting and documenting all project requirements. System Design – Creating architecture and design based on requirements. Implementation (C…  ( 6 min )

Learning a new skill is never easy; and programming has proven to be one of the hardest challenges I’ve faced. I began my coding journey in 2024 when I joined ALX, knowing nothing but eager to write those magical lines of code that bring apps or games to life. But reality hit me very fast. We began with Shell basics, which were smooth, then moved to C language, which humbled me. Starting C, I thought: “If I can print Hello, World!, then I can do anything.” On came about functions, pointers and arrays which didn’t just confuse me but crush me to the pits. Instead of truly learning, I took shortcuts: copying code just to pass. Soon, I was drowning in recursion, data structures, and memory allocation without understanding the foundations. By June 2024, I knew I had to take a step back: I felt guilty, defeated, and convinced maybe programming wasn’t for me. Still, the dream never left. After months of reflection, I realized the first thing I needed to fix wasn’t my code; it was my mindset. Now, as I restart my journey, I come better prepared: mentally, emotionally, and practically. I know there will be long nights of debugging. I know errors will test my patience. But I also know this: quitting isn’t an option anymore. This time, my path is clear: Progress >>> Perfection.  ( 5 min )

When most people imagine Data Science, they picture building shiny machine learning models or crafting beautiful dashboards. if your data is messy, no model can save you. That’s why people say: “80% of a data scientist’s time is spent cleaning data.” And it’s not a joke. Missing values → blank cells, NaNs, or inconsistent entries. Duplicates → one user recorded multiple times. Outliers → extreme values like a salary of $1,000,000,000. Inconsistent categories → Nairobi, NBO, 254-Nairobi treated as different. Wrong data types → numbers stored as text. Here’s how I usually tackle some of these: import pandas as pd # Example dataset data = { "Name": ["Alice", "Bob", "Charlie", "Alice"], "Age": [25, None, 37, 25], "Salary": [50000, 60000, 1000000000, 50000], # notice the outlier "City": ["Nairobi", "NBI", "254-Nairobi", "Nairobi"] } df = pd.DataFrame(data) print("Before Cleaning:") print(df) # 1. Handle missing values df["Age"].fillna(df["Age"].median(), inplace=True) # 2. Drop duplicates df.drop_duplicates(inplace=True) # 3. Fix inconsistent categories df["City"] = df["City"].replace({"NBI": "Nairobi", "254-Nairobi": "Nairobi"}) # 4. Handle outliers (example: cap salaries above 200k) df["Salary"] = df["Salary"].apply(lambda x: min(x, 200000)) print("\nAfter Cleaning:") print(df) Before Cleaning: Name Age Salary City 0 Alice 25.0 50000 Nairobi 1 Bob NaN 60000 NBI 2 Charlie 37.0 1000000000 254-Nairobi 3 Alice 25.0 50000 Nairobi After Cleaning: Name Age Salary City 0 Alice 25.0 50000 Nairobi 1 Bob 25.0 60000 Nairobi 2 Charlie 37.0 200000 Nairobi Don’t ignore missing values, understand the why before filling/dropping. Standardize categories early to avoid “ghost” groups. Outliers may be errors or real rare events, investigate before deleting. A clean dataset can outperform a complex model trained on dirty data.  ( 6 min )

Early-stage startup founders live in constant motion such as pitching investors, refining products, and fighting for traction. In this hustle, customer relationships often take a back seat. Yet ignoring them early can be one of the costliest mistakes. Three reasons stand out: Acquisition costs are rising. Customer acquisition cost (CAC) for SaaS has jumped more than 60% in five years, making paid ads unsustainable. Investors expect clarity. By Seed or Series A, you need metrics like CAC, LTV, churn, and funnel conversion. Without a system in place, these numbers are messy or missing. That is why customer relationship management (CRM) must be seen not as software you buy later, but as the foundation of growth.

ℹ️ Re-posted from stripe.dev While working remotely and traveling from place to place, I noticed a recurring pattern. Every time you arrive in a new city, you rent an Airbnb or check-in to a hotel. Then you sign up for a gym and a co-working space. Payments for these services are all done electronically. But when it comes to access, you need a plastic card, a fob, or a physical key. This creates friction for everyone involved. You have to go pick it up, carry it around, hope you don’t lose it, and return it before leaving. From the business side, they need to pay someone to work the front desk to issue, track, and collect these access devices. This made me wonder, what if access was fully digital? Luckily, there is a better way that is gaining popularity. Instead of cards and keys, w…  ( 9 min )

CREATE DATABASE CollegeDB; 👩‍🎓 Step 2: Creating the Tables We’ll need 3 main tables: Students – to store student details Courses – to store course details Enrollments – to link students with courses Students Table -- Courses Table -- Enrollments Table (Relationship) 📝 Step 3: Inserting Data Let’s add some sample students and courses. -- Insert Students rahul@college.edu', '9876543210'), priya@college.edu', '9876501234'), amit@college.edu', '9876523456'); -- Insert Courses -- Enroll Students into Courses 🔍 Step 4: Querying the Database Now the fun part – let’s ask our database questions! Show all students Find all courses taken by Rahul Kumar Count how many students are in each department Find top performers (students with Grade 'A') ⚡ Step 5: Updating & Deleting Data Rahul changed his phone number? Let’s update it. UPDATE Students Want to remove a student completely? 🎯 Step 6: Why This System Matters This Student & Course Management System is not just a practice project — it’s the foundation of real-world college ERP systems. Colleges use it to manage admissions, courses, results, and fees. You can extend it with features like faculty details, attendance tracking, and exam results. Add a web or app interface and you’ve got a full-fledged college management software! 🚀 Final Thoughts We just built a mini college ERP system using SQL. You now know how to: This project is a perfect mini-project for college students in DBMS, SQL, or Software Engineering courses.  ( 7 min )

Hollow Knight: Silksong Preview – gamescom 2025 Hollow Knight: Silksong, Steam’s most wishlisted game, got its spotlight at gamescom 2025 with a demo featuring two contrasting stages: the breezy Moss Grotto and the punishing Deep Docks. Playing as Hornet instead of the Knight brings faster, sharper combat and fresh traversal tricks that shake up the familiar Metroidvania formula. From effortless platforming in the Grotto to near-heartattack moments in the Docks, Silksong delivers on its hype, balancing accessibility for newcomers with enough spike-filled challenges to satisfy series veterans. If you loved Hollow Knight’s brutal charm, get ready for hornet-stung thrills. Watch on YouTube  ( 5 min )

The Enigmatic 'this' Keyword in JavaScript JavaScript's 'this' keyword is a source of confusion for many developers, but unraveling its mysteries can lead to a deeper understanding of the language's inner workings. Global Scope When used in the global scope, 'this' refers to the global object, which in a browser is the window object. console.log(this === window); // true Object Methods Within an object method, 'this' refers to the object itself. const person = { name: 'John', greet() { return Hello, ${this.name}!; } }; console.log(person.greet()); // Hello, John! Constructors When used in a constructor function, 'this' refers to the instance being created. function Car(make) { this.make = make; } const myCar = new Car('Toyota'); console.log(myCar.make); // Toyota Event Handlers In event handlers, 'this' typically refers to the element that triggered the event. document.querySelector('button').addEventListener('click', function() { console.log(this.textContent); }); By understanding the various contexts in which 'this' is used, developers can harness its power to write more effective and efficient JavaScript code.  ( 5 min )

Intro In one of my previous posts, I wrote about features between Java LTS versions 21 and 17. Now, two years later (how!? Two years already!?), a new LTS version is scheduled for release on September 16, 2025 — Java 25. Today, it has moved into the "Final Release Candidate" phase, and the feature set is frozen. The vast majority of projects skip non-LTS releases and use Java LTS versions only. So, let's take a look at the features that the new LTS version (Java 25) delivers compared to the previous LTS version (Java 21). I will be using the following abbreviations for the feature states in the tables below: exp = Experimental inc[2|3|4|etc] = Incubator [2|3|4|etc] pre[2|3|4|etc] = Preview [2|3|4|etc] prod = Production w/d = Withdrawn Feature Java 21 Java 22 Java 23 Java 24 Java 25 …  ( 17 min )

Software development is often portrayed as a purely logical discipline, one where success is measured in clean code, robust frameworks, and seamless deployments. Yet, anyone who has spent time working on a team of developers knows that the human side of the profession is just as influential as the technical side. Emotional intelligence—the ability to recognize, manage, and respond to emotions effectively—has become an increasingly relevant factor in shaping not just productivity but also workplace culture. Interestingly, many of the principles that underpin effective counselling can be applied to the software industry, and the Professional home at Bull Creek Counselling Centre offers valuable insights worth considering. Emotional Intelligence in the Tech Workplace Defining Emotional Inte…  ( 7 min )

If you've ever pushed a change to production and your browser stubbornly kept showing you the old version, you've experienced caching, probably not in a good way. HTTP caching is one of those topics that can seem deceptively simple ("it just stores stuff locally"), but the details matter. Done right, it makes sites feel lightning-fast and reduces server load. Done wrong, it causes confusing bugs and outdated resources to linger. This isn't a deep dive into every caching strategy, it's the quick, developer-focused overview I wish I had when I first started building for the web. At the end, you'll find resources for going deeper. Fetching resources over the network is slow and expensive, not just in terms of latency, but also in wasted bandwidth and server strain. Caching lets us store a…  ( 11 min )

I’ll be honest. Few things are more frustrating than solving a problem by reaching for a great package… only to realize the problem is still there. That was me last week, yelling at my API like it had just spoiled the finale of a Netflix show. I was using Spatie’s Laravel ResponseCache package. It’s rock solid, it works out of the box, and it’s built by people I trust. But here’s the kicker: I turned it on in production and suddenly my multilingual API was speaking one language only. The first request cached in English. Every Arabic request after that? Still English. So here’s what it took to fix it. I hope it will help some lost soul on the internet one day.

As developers, we spend weeks (sometimes months) training, fine-tuning, and deploying AI models. But here’s the uncomfortable truth: Once they’re live… do we really own them? On most platforms, your AI ends up locked inside someone else’s infrastructure: Behind APIs, you don’t fully control Running on servers you don’t own Generating value that mostly flows back to the platform, not you That doesn’t feel like ownership. At haveto.com, we think your AI should be more than just code. Here’s how it works when you deploy AI directly on-chain with us: ✅ Your AI gets its own wallet → it earns every time it completes a task. ✅ On-chain identity → proof of ownership is transparent, forever. ✅ Portability → sell, lease, or license your AI like a real IP. This isn’t “another hosting service.” Deploy AI on-chain, earn directly from users, no middlemen. True IP protection — no one can copy-paste your model into their cloud. Cost efficiency — gas fees drop as usage grows (a real economy of scale). You’re not just pushing code anymore — you’re creating revenue-generating IP. AI runs directly on the blockchain (no third-party servers). Transparent + verifiable outputs (great for finance, healthcare, and other trust-heavy domains). Secure, scalable, and designed for real workloads. 1️⃣ Build your AI model in any language (Python, JS, Rust, we don’t force you into one). 💭 Question for the dev.to community: 👇 Let’s discuss. 🔗 haveto.com  ( 6 min )

When it comes to cloud migration, businesses are faced with a big decision: how to move their IT infrastructure and applications to the cloud. A cloud migration strategy allows companies to take advantage of flexibility, scalability, and cost savings. But before you dive in, it’s essential to understand the different strategies available for migrating to the cloud. These strategies are often referred to as the 7Rs of Cloud Migration Strategy. In this article, we’ll walk you through what each strategy involves, and how businesses of all sizes and technical levels can approach cloud migration. Simply put, cloud migration is the process of moving applications, data, and other business elements from on-premise servers (physical servers) to cloud infrastructure.

HTTP status codes are like the server sending you a quick text back when you’re building websites or apps. Every time your browser or app asks for something, the server replies with a three-digit number that tells you if everything worked, something went wrong, or you need to do something else. Knowing these codes helps you fix problems faster, keep an eye on your app, and make sure it works reliably. Before we get started, don’t forget to subscribe to my newsletter!

When I first started attending conferences, I diligently tried to write down notes and publish them. It forced me to actively listen to the talks I was attending. With the number of conferences rising, I couldn't keep the rhythm. When I switched my career path to Developer Advocate, I drastically diminished the number of talks I attended in favor of the hallway track. As a result, the last conference "report" I wrote was JPrime's in 2022. This week, I was privileged to speak at DevOps Days Kansas City. The event was co-located with and part of KCDC. It was my first edition for both. As I'm returning to engineering, the number of conferences I'll attend in the near future will probably be very low, if not zero.

I didn’t put this article at the start of your journey - in my opinion, it’s hard to choose where you’re going if you haven’t yet seen what the road looks like, what challenges lie ahead, or who you’ll be walking beside. Now that you’ve already explored some of the core ideas of cybersecurity ( threats, frameworks, ethics, risk) - it’s the perfect moment to step back and ask: What kind of security professional do I want to become? When most people hear the word "cybersecurity", they picture someone in a hoodie hammering away at a keyboard in a dark room. In reality, though, cybersecurity is much more than just hacking or stopping hackers. It’s a vast and constantly evolving field, made up of many disciplines - each with its own tools, challenges, and mindset. Think of it like a city - the…  ( 12 min )

Hi there 👋, I have just started a mentorship journey with my manager to enhance and level up my backend and system design skills. The first challenge on my plate: Uber Now, I'm actually not building the next Uber😅 but I’ll be breaking down how such a huge system works and how to make it scalable, reliable, and fun to learn from The Game Plan (REC 🎯) My mentor gave me a simple framework to guide my thinking: R = Requirements → What exactly should Uber do? E = Environment → Who’s using it, where, and under what conditions? C = Constraints → What limits (time, money, resources, etc.) affect the design? This little formula (REC) will help me avoid running wild with random ideas and instead focus on real engineering decisions. What I’ll Be Doing Over the next two weeks, I’ll: Break down Uber’s requirements, environment, and constraints. Sketch out an architecture design. Share updates through blog posts like this. Present the design to my mentor Why Blog About This? That’s it for Day 1. Stay tuned — it’s going to be fun breaking it all down! 🙌  ( 5 min )

Developers love the rush of getting something working fast. A quick proof-of-concept, a few shortcuts, and suddenly you have something that looks ready. But moving vibe-coded prototypes straight into production is one of the fastest ways to sink a project. In the short term, it feels like you are saving time. In reality, you are borrowing from the future, and the interest rate on technical debt is brutal. Vibe coding is all about momentum. You write code quickly, often with AI-assisted tools or borrowed snippets, focusing on functionality over structure. It is perfect for early experiments, demos, and validating ideas. The problem is that vibe-coded systems are rarely built for: High concurrency Maintainability by a growing dev team Regulatory compliance Reliable performance under load …  ( 6 min )

Amortisation Explained Simply: How Your Loan Payments Are Split Between Interest and Principal When you take out a loan—whether it’s a mortgage, car loan, or personal loan—you’ll often hear the term “amortisation.” At first, it might sound like complicated financial jargon. But the idea is actually quite simple: amortisation is just the process of spreading out your loan repayments over time. Understanding amortisation is crucial because it shows you exactly how much of your monthly payment goes toward interest (the bank’s charge for lending you money) and how much reduces your principal (the actual amount you borrowed). Let’s break it down step by step. Principal: The original amount you borrow (say, \$200,000 for a home loan). Interest: The cost of borrowing, usually expressed as an a…  ( 6 min )

After my 4th semester, reality hit me like a truck: “oh crap, I need to get an internship.” I applied everywhere, gave interviews, fumbled half of them, got disappointed… and finally landed an offer. Which I refused. Out of pure confusion. Then, like the clown I was, I called them back, apologized, and somehow still got the internship. At first, I was excited. Corporate life looked shiny and glamorous in my head. I chose the Full Stack department, pumped to finally do “real dev work.” …And then reality smacked me again. The work? Mundane, boring tasks. The devs? Sitting at their desks from morning to evening like NPCs on repeat. Watching them, I thought: “Wait… is this going to be my whole life??” That’s when the depression arc kicked in.

When was the last time you downloaded an app and deleted it within minutes because it crashed, froze, or simply didn’t feel reliable? You’re not alone-according to a 2023 TechRadar survey, 70% of users uninstall an app within a week if they encounter performance issues. That’s the brutal reality of the digital world: users have zero patience for buggy apps. This is exactly where mobile app test automation comes in. I still remember working on my first mobile project as a junior tester. It was a simple e-commerce app, and everything looked fine during manual testing. But once the app hit the real world—with hundreds of devices, OS versions, and unpredictable user behaviors-it fell apart. Cart errors, login glitches, and payment bugs all showed up within days. It was painful. That was my wak…  ( 8 min )

Hey friends 👋, Today I started the OverTheWire Bandit challenges — a playground where you learn real Linux + security skills by solving tiny puzzles. It felt like a game where each level teaches you one new “hacker move.” Here’s my journey from Level 0 to Level 4, explained like I’d tell a friend. At first, I had no idea what SSH was. After running man ssh, I learned: SSH (Secure Shell) lets you control another computer securely from far away. To connect to Bandit, I used: ssh -p 2220 bandit0@bandit.labs.overthewire.org # password: bandit0 This dropped me into another computer like stepping into a remote terminal. Boom 🎉, Level 0 cleared.

Sending high-volume emails is common for large organizations. They need to reach employees, customers, or both. Some use mailing services like Mailchimp, SendGrid, or MailerLite. Others prefer to handle bulk emails in-house. If your organisation uses Microsoft 365, recent changes may affect you. Microsoft has introduced new restrictions on high-volume emails to improve security and system stability. As a result, many businesses are rethinking their email strategy. In this article, I’ll explore two Microsoft solutions for high-volume email: High Volume Email (HVE) – A built-in option within Microsoft 365.

If you need to back up or move your MySQL data quickly, mysqldump is the tool for the job. It exports databases, tables, or just the schema into SQL scripts that can be restored anywhere. This guide shows how to use it with common examples and must-know options. mysqldump -u admin company > company_backup.sql mysql -u admin new_company data.sql mysqldump -u admin company --no-data > schema.sql mysqldump -u admin company --tables orders products > tables.sql -routines: Includes stored procedures -events: Exports event scheduler definitions -lock-tables: Locks during dump (default for MyISAM) -single-transaction: Faster, consistent backups for InnoDB -result-file: Use instead of > for better encoding on Windows By default, mysqldump writes to standard output. To save the dump to a file, use redirection like > dump.sql or the --result-file=dump.sql option. On Windows, it’s typically found under: Yes. Use --host (or -h) to specify the remote server's address. Ensure remote access is enabled and credentials are correctly provided. You need SELECT for tables, SHOW VIEW for views, and TRIGGER for triggers. Extra privileges may be required depending on options used. mysqldump is one of the most important tools in a MySQL user's toolkit. It’s ideal for quick dumps, full backups, or schema exports. With the right flags, you can ensure fast, consistent results every time. Prefer GUI? DbVisualizer lets you export entire databases in just a few clicks—perfect for those who want power without the CLI.

Inspired by @ihssmaheel and his guide to Rust for JavaScript developers I decided to start learning this general-purpose programming language from scratch. Of course, I do know other languages, but JavaScript is the one I’m using every day at work for years. I’ll share my progress with you in this beginners-oriented series. Before proceeding, here’s what I’m going to do: I plan to follow The Rust Programming Language, but in its forked version published by the Brown University. I chose to do so, because this one is more interactive than the original version, and I think it would be better for me. It’s also recommended by the language maintainers.

So you’ve decided it’s finally time to get serious about interview prep. No more winging it, no more hoping the recruiter skips system design questions, no more “I’ll just figure it out during the interview” (spoiler: you won’t). You start Googling resources and bam, you stumble on Hello Interview, a relatively new platform promising to help you crush technical interviews with curated guides, mock interviews, and system design practice. But here’s the real question: Is Hello Interview worth it? Or is it just another subscription you’ll add to the pile, right next to your half-finished Udemy courses and that Pluralsight trial you forgot to cancel?

So you’ve decided to stop doomscrolling and actually learn something online. Nice. You fire up Google, type in “best online courses,” and suddenly two names dominate your screen: edX vs Coursera. But here’s the real question: which one actually helps you learn something useful, and not just collect another PDF certificate you’ll forget to add on LinkedIn? I’ve tried them both (usually while over-caffeinated and under-slept), so let’s break it down. edX It feels a lot like traditional education went online. Courses are structured, professors are legit, and the branding screams “serious student vibes.” Coursera It’s more of a mix: part academic, part career-focused. Want to learn AI?

If you’re building a new product, website, or app, choosing the right content management approach can save you a lot of time and scaling issues later. Traditional CMS platforms like WordPress work well initially but can limit flexibility as your needs grow. This is where Headless CMS comes in. What is a Headless CMS? A Headless CMS is a content management system where the backend (content storage) is separated from the frontend (your website or app). Instead of using built-in themes, you connect your CMS to frameworks like Next.js, React, or Vue.js via APIs. Benefits for Startups & Developers Flexibility: Design your frontend exactly how you want without CMS restrictions. Scalability: Your content can be reused across websites, apps, and other platforms. Faster Development: Developers can use modern frameworks and workflows. Future-Proof: Since the frontend and backend are decoupled, you can upgrade or replace one without breaking the other. Popular Headless CMS Options Here are some beginner-friendly and powerful Headless CMS platforms to explore: Sanity.io – Great for real-time collaboration and flexible APIs. Builder.io – Visual editor combined with headless CMS features. Contentful – A popular enterprise-ready CMS. When to Use Headless CMS? If your project needs custom frontend, supports multiple platforms (web + mobile), or requires high scalability, then headless CMS is a strong choice. Startups benefit because it avoids lock-in and allows teams to grow their tech stack over time. Pro Tip Pair your Headless CMS with frameworks like Next.js or Nuxt.js for smooth rendering and SEO-friendly performance. Note: If you’re a startup or developer exploring headless CMS solutions, working with an experienced web development company can make the integration process much easier. Companies like RW Infotech specialize in modern development stacks and headless CMS implementation. https://www.rwit.io/service/web-development  ( 6 min )

What is an SIEM Tool? The acronym for a security information and event management technology is SIEM. This cybersecurity solution gathers and tracks logs from all of an organization's IT systems to assist in identifying, evaluating, and responding to security threats.

SurrealDB: shiny newcomer, low-level database, or both? SurrealDB is admittedly a pretty shiny database. It's built in Rust, a programming language that has just barely hit the 10-year mark since it hit version 1.0. A good deal of attention is paid to the website and brand design, and the official Surrealist app is not only slick but even capable of visualizing data as an interconnected net of records. This blog post goes into further detail on how this graph visualization works, leading to output like the following that lets you see which European countries belong to which intranational groups. But the other side of being a database written in a low-level language like Rust is that you can compile it to machine code with a single command and do everything you want with it on the comman…  ( 21 min )

🚀 My Journey with SQL on Oracle LiveSQL | Assignment Practice As part of my DBMS assignment, I decided to go hands-on with Oracle LiveSQL and practice real-world SQL queries. What started as just another task turned into an exciting journey of creating tables, inserting data, altering structures, and running some powerful queries. Let me walk you through my experience! 🏗 Step 1: Creating Tables I began with three main tables: Students – to store student details Courses – to hold course information Enrollments – to manage the many-to-many relationship between students and courses CREATE TABLE Students ( CREATE TABLE Courses ( CREATE TABLE Enrollments ( 📸 Screenshot proof of successful table creation: ✍️ Step 2: Altering & Inserting Data Next, I added a Phone Number column to the Students table and inserted some sample data. ALTER TABLE Students ADD (PhoneNo VARCHAR2(10)); INSERT INTO Students (StudentID, Name, Dept, DOB, Email) VALUES alice@example.com'), bob@example.com'), charlie@example.com'); 📸 Screenshot proof of inserted rows: I queried all student names in uppercase and calculated the length of their email IDs: SELECT UPPER(Name) AS StudentName, LENGTH(Email) AS EmailLength ✅ Output: STUDENTNAME EMAILLENGTH 📸 Screenshot of results: I also tried aggregate functions to calculate the average credits of courses and the total number of students: SELECT AVG(Credits) AS AvgCredits, COUNT(*) AS TotalStudents 📸 Screenshot output: 💡 Key Takeaways SQL is more powerful than it looks – even small queries give deep insights. Working with constraints (PRIMARY KEY, FOREIGN KEY, UNIQUE, CHECK) is essential for maintaining data integrity. Oracle LiveSQL is a fantastic tool for learning + testing SQL without needing local installation. 🎯 What’s Next? This was just the beginning! My next steps will include: JOIN queries to link Students and Courses. GROUP BY with HAVING for department-wise insights. Views & Stored Procedures to wrap logic neatly. Stay tuned for Part 2 of my SQL journey 🔥  ( 6 min )

What is Pub/Sub? Publish/Subscribe (pub/sub) is a messaging pattern where publishers send messages without knowing who will consume them, and subscribers receive messages without knowing who produced them. A broker (like Kafka, RabbitMQ, SQS, Redis) usually sits in the middle to handle message delivery. This decoupling allows systems to communicate asynchronously and scale independently. Pub/Sub solves several common problems in distributed systems: Decoupling – Publishers don’t need to know subscribers. Scalability – Multiple subscribers can process messages independently. Reliability – Messages are queued until consumed (depending on broker). Flexibility – One message can be delivered to many subscribers (fanout). When Pub/Sub? Use pub/sub when: You want event-d…  ( 6 min )

But here’s the reality: as business ecosystems become more real-time and API-driven, EDI on its own often struggles to keep up. Why Traditional EDI Falls Short While EDI is reliable, it wasn’t built for the modern pace of business. Companies often face: Integration delays — onboarding new trading partners can take weeks. High costs — managing legacy VANs and middleware eats into budgets. Lack of real-time visibility — data often lags, leading to shipment errors or delayed payments. According to Gartner, 60% of organizations still rely on legacy EDI systems, but more than half plan to modernize their B2B integration stack within the next 3 years. APIs as the Next Step APIs don’t replace EDI entirely—but they enhance it. Modern B2B networks now combine EDI’s structure with API’s speed and flexibility. This hybrid approach ensures compliance while enabling real-time data exchange. Benefits include: Faster onboarding of trading partners. Instant updates on order statuses and shipments. Lower integration maintenance costs. The Rise of Cloud-Native EDI Platforms Instead of building and maintaining complex EDI infrastructure in-house, companies are turning to cloud-native EDI solutions. These platforms provide: Plug-and-play integrations. Automated validation of EDI messages. Real-time monitoring and error handling. This shift allows IT teams to focus less on firefighting and more on strategic initiatives. Platforms like ORDERFUL are helping businesses make this transition with flexible, API-first EDI solutions. Final Thought EDI isn’t dead—it’s evolving. The future of B2B integration lies in hybrid ecosystems where APIs and EDI coexist seamlessly. Companies that adapt now will be positioned to thrive in an increasingly digital supply chain.  ( 6 min )

One of the biggest myths about learning is that you need endless hours to master new skills. I’ve read over 1,500 books in the last 15 years, but nothing has accelerated my learning like using AI as a personal learning assistant. Here’s my system. 1️⃣ Summarise Smarter, Not Harder Instead of slogging through 300 pages, I use ChatGPT to: Summarise key chapters Highlight arguments and counterarguments Create mind maps 💡 Prompt: “Summarise [article/book/paper] into 5 bullet points, 2 examples, and 1 key action takeaway.” 2️⃣ Turn Notes Into Action Most people stop at highlights. I turn notes into checklists and exercises with AI. 💡 Prompt: “From these notes, create a 7-day action plan to apply the concepts in real life.” This way, learning becomes practice — not just theory. 3️⃣ Debate With AI When I don’t fully understand a topic, I argue with ChatGPT. “Act as a skeptic. Challenge my understanding of [topic] with 5 tough questions. Then help me refine my answers.” This forces deeper clarity and confidence. 4️⃣ Create Learning Systems I build structured learning plans with AI, like: Weekly reflection exercises Project-based challenges 📂 Resource: On the ReThynk AI YouTube Channel, I share live tutorials on how to design these AI-powered learning systems. 5️⃣ Teach Back What I Learn The fastest way to know if you’ve learned something? Teach it. 💡 Prompt: “Pretend you’re a 15-year-old beginner. Ask me 5 questions about [topic], and help me refine my explanations if they’re unclear.” Tools I Use Alongside AI Notion + AI → Smart knowledge management Readwise → Sync highlights from books/articles ChatGPT → Tutor, coach, and challenger ReThynk AI Templates & Frameworks → My pre-designed learning structures ReThynk AI Magazine → Curated AI & business insights (currently free on our website) Final Thought In a noisy world, the advantage doesn’t go to those who consume more — it goes to those who learn faster and apply smarter. 📌 Next Post: “5 Mistakes People Make with ChatGPT Prompts” — and how to avoid them.  ( 7 min )

Curiosity about real-world cyberattacks-like how huge botnets for DDoS attacks form-pushed me beyond the classroom. The only way to really learn was to spin up my own honeypot and watch the attackers come at me. To reach my goal, I started out with Cowrie, then later moved on to Dionaea and integrated everything with Splunk + Tailscale. The first priority was security, so I moved the SSH port into the 53,000 range and set up Tailscale VPN to give my laptop a stable IP and restrict access. I began with small Cowrie experiments, which went surprisingly smoothly aside from some networking and config hiccups. That success gave me the confidence to step up to Dionaea — a bigger challenge.

In The Mythical Man-Month, Fred Brooks famously wrote: The magic of myth and legend has come true in our time. One types the correct incantation on a keyboard, and a display screen comes to life, showing things that never were nor could be. In 1975, that was programming itself; type the right sequence of symbols and something new appeared. Today, we’re living through a new version of that magic. With large language models, you don’t even need the exact incantation. A vague prompt - a vibe - can conjure up working code. It feels like we’ve entered what I like to call The Mythical Vibe-Month: a world where AI gives us the illusion of infinite acceleration.

Technical debt isn't just a developer problem—it's a business problem with a real price tag. Let's break down what technical debt actually costs a typical 10-developer team: Developer Time Breakdown: Average developer salary: $120K Total cost (including benefits/overhead): $180K per developer Team cost: $1.8M annually Time Allocation Research Shows: 23% of developer time spent on technical debt (StripeReport 2023) 17% on debugging production issues 40% total "maintenance" vs. feature development The $180K Annual Loss: $1.8M × 40% maintenance time = $720K Minus necessary maintenance (20%) = $360K excess Conservative estimate of recoverable waste: $180K But that's just the beginning... Technical debt compounds like financial debt. Teams that don't address it see: Velocity Decay: 15% slower feature delivery year-over-year Quality Tax: 60% more production incidents Developer Churn: 40% higher turnover in teams with high tech debt Smart engineering leaders are now tracking: Technical debt velocity (issues resolved vs. introduced) Feature delivery time trends Production incident root cause analysis Traditional approaches (quarterly "tech debt sprints") fail because: They're reactive, not proactive They compete with feature work for priority They require expensive developer time Forward-thinking teams are exploring automation: Automated code quality enforcement AI-powered refactoring suggestions Continuous debt remediation How much is technical debt costing your team? Try this quick calculation: (Team Size × $180K) × (% Time on Maintenance - 20%) = Annual Tech Debt Cost Share your results in the comments—you might be surprised by the number.

Unleashing the Power of Hyperparameter Tuning: A Journey into Grid Search Imagine you're baking a cake. You have the recipe (your machine learning algorithm), but the perfect cake depends on the precise amounts of each ingredient (your hyperparameters): the oven temperature, baking time, amount of sugar, etc. Getting these just right is crucial for a delicious outcome. This, in essence, is hyperparameter tuning. And Grid Search is one powerful technique to help us find that perfect recipe. Hyperparameter tuning is the process of finding the optimal set of hyperparameters for a machine learning model to achieve the best possible performance. Hyperparameters are settings that are not learned from the data during training, unlike the model's parameters (weights and biases). They control the…  ( 9 min )

Let’s be real: picking between Ethereum and NEAR for your next blockchain adventure? It’s a big deal—like choosing between a cat and a dog.

Hello Everyone! After a while away from publishing, I’m back — this time to share something very different from my usual reflections on leadership or career. If you expect a story about a lone wolf who coded the next billion-dollar SaaS in his basement, forget it. This is not that story. I’ve tried launching MVPs before. Ideas that started with excitement, prototypes that felt promising… but they always stalled. They stayed in that “almost something” limbo. t’s a social recommendation platform — a place where people share books, movies, and music they love, not just what algorithms decide. A network built around human taste, not corporate feeds. And here’s the interesting part: RecomendeMe was shaped by the messy but fascinating collaboration between human creativity and artificial intelli…  ( 11 min )

Before we deep dive, let's learn a couple of important concepts Sockets are endpoints for communication between computers over a network, enabling real-time data exchange. Unlike regular files, sockets do not store data but facilitate data transfer between machines. When Go requests a socket from the operating system (OS), the OS creates the socket and assigns a unique identifier called a file descriptor. A file descriptor is an integer handle that the Go server uses to manage and reference the socket. This mechanism allows the server to efficiently send and receive network data through OS-managed resources. Go uses goroutines, lightweight threads, to handle many client requests concurrently. The main goroutine continuously waits for incoming requests. For each new request, Go creates a new goroutine to process it independently without blocking the main one. This design ensures the server remains fast and scalable, handling multiple clients simultaneously. When no requests arrive, the main goroutine sleeps to conserve system resources and improve overall efficiency. The kernel is the core part of the operating system that manages hardware and processes. Network requests first travel through a router and then reach your computer’s Network Interface Card (NIC), like a WiFi adapter or Ethernet port. The NIC converts the wireless or wired signals into binary data and temporarily stores it in a buffer. It then sends a signal to the kernel to process this new data. The kernel copies the data into a socket buffer that the Go server listens to, and marks it ready for reading. The Go runtime wakes up the goroutine to read and process the request. The server sends the response back through the socket and NIC. The response reaches the client’s browser.  ( 6 min )

KIB in Batch I made KIB in Batch, which is a lightweight UNIX-like environment for Microsoft Windows. The automatically generated standalone batch file (creates all needed files and runs the main script) weighs less than 500 kilobytes! Installing KIB in Batch is quite simple. You must go to https://github.com/KIB-in-Batch/kib-in-batch/releases/latest and download kib_in_batch.zip. You may use this over other UNIX-like environments for IoT devices, which have very limited resources. Cygwin, Msys2 and WSL are heavy. You may also use this when SSHing to a Windows Server. https://github.com/KIB-in-Batch/kib-in-batch https://github.com/KIB-in-Batch KIB in Batch is a recursive acronym.

In 2025, software teams face one recurring challenge: building scalable, maintainable code that doesn’t collapse under complexity. While frameworks, languages, and paradigms evolve rapidly, one principle has remained surprisingly timeless: pure functions. Pure functions are at the core of functional programming (FP), and they’re quietly shaping the future of how developers think about code. If you’re still relying heavily on stateful, side-effect-heavy practices, it might be time to reconsider—because pure functions are no longer just “academic theory”; they’re practical, profitable, and powerful. A pure function is one that: Always returns the same output for the same input. Produces no side effects (like changing global state, modifying data outside its scope, or interacting with the ex…  ( 6 min )

Introduction You have done everything right. Your team has modernized to Java 17 LTS, your builds are clean, your Flink job compiles without warnings, and you have successfully pushed it to Amazon Managed Service for Apache Flink. You sit back, expecting smooth sailing, only to watch your job crash with this cryptic message: has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0 If you are staring at this error right now, you are not alone - and you are definitely not doing anything wrong. The error message above is Java's way of saying "I cannot run code that was compiled with a newer version than me." In this case, your Flink job was compiled with Java 17 (class file vers…  ( 9 min )

Event-driven systems are powerful — but testing them can feel heavy. Spinning up a Kafka cluster, checking if specifications are met, producing test input, and reading results from topics… it adds a lot of overhead, especially in CI pipelines. What if you could test Kafka workflows without running a Kafka cluster? That’s exactly what Mokapi enables. Testing event-driven workflows usually means juggling infrastructure: Running a local or containerized Kafka broker Making sure topics and schemas match the spec Setting up test producers and consumers Verifying results at the topic level For end-to-end workflow tests, this slows you down. With Mokapi, you can skip the cluster and use a Kafka-like REST API for producing and consuming records — perfectly aligned with your AsyncAPI specs. Le…  ( 6 min )

Written by Josh Skorich and originally posted on spektion.com Working closely with both offensive security teams and on the front lines of runtime visibility at Spektion, I've seen a new approach to threat management take shape. Instead of relying on signatures or static patterns, the most effective security strategies today are grounded in real-time behavioral intelligence: insights drawn directly from how software actually runs. This isn't just another incremental improvement in detection technology. It's a paradigm shift that's exposing entirely new categories of risk and enabling proactive identification of threats that would have remained invisible under conventional approaches. Most security tools today rely on what I call "signature thinking": the assumption that threats can be iden…  ( 10 min )

Check it out, if that’s your kind of thing. In object-oriented programming (OOP), one of the most common questions developers face is how to reuse code effectively. Traditionally, inheritance has been the go-to mechanism: a class extends another, reusing its methods and properties while adding or overriding behavior. But inheritance, while powerful, comes with pitfalls—tight coupling, rigid hierarchies, and difficulty in adapting to new requirements. To address these challenges, the principle of composition over inheritance has emerged as a cleaner, more flexible alternative. Inheritance allows classes to sh…  ( 8 min )

Did you know that Netflix has over 76,000 genres to categorize its movie and tv show database? I am sure this must be as shocking to you as this was to me when I read about it first. Genres, rather micro-genres, could be as granular as “Asian_English_Mother-Son-Love_1980.” This is the level of granularity to which Netflix has segmented its product offerings, which is movies and shows. I think the success of Netflix answers this question on its own. Netflix is considered to have one of the best recommendation engines. They even hosted a competition on Kaggle and offered a prize money of USD 1 million to the team beating their recommendation algorithm. This shows the sophistication and advanced capabilities developed by the company on its platform. This recommendation tool is nothing but a s…  ( 11 min )

The limits of LLMs are clear, and the criticisms are valid. They lack true reasoning, a genuine grasp of cause and effect, and often hallucinate. This sparks the great debate in AI: can we achieve AGI simply by scaling these models to unimaginable sizes, triggering a dramatic emergence of intelligence? Or do we need fundamentally new models capable of genuine reasoning and understanding reality? Perhaps the best way to view LLMs is as the Neanderthals of the AI world. Neanderthals were not primitive brutes; they were the apex of their era. They were intelligent, adaptable, and masters of their domain. Similarly, LLMs represent the peak of our current capabilities. Yet, Neanderthals were not the final form of humanity. They were eventually succeeded by Homo Sapiens, a species with superior abstract thought and planning. In the same way, LLMs, for all their power, are not the final form of AI. They will inevitably be succeeded by new models capable of the true reasoning and abstract planning they currently lack. And just as Neanderthal DNA lives on within us, the foundational principles of LLMs will forever be part of AGI's architecture. Ultimately, LLMs are not the destination. They are the inevitable path, the absolute foundation, and the necessary ancestor on the journey to AGI. We must pass through their era to reach our own Homo Sapiens.  ( 5 min )

As a backend engineer, my goal isn't just to build features that work, but to make them fast and scalable. One of the most frequent performance issues I've encountered and one I see a lot of developers run into is the N+1 query problem. It's a subtle bug that can cripple an application's performance. In this post, I'll break down what this problem is, show you its real-world impact from my own experience, and walk you through the exact solution I use with Go and SQL. Let me set the scene with an example I ran into while working on an e-commerce application. I was building a feature to display a user's order history. Each order was tied to a specific product. My initial code fetched the user's 50 most recent orders. Then, to get the product name for each order, my code made another database…  ( 8 min )

Coding is not just about writing syntax and fixing bugs. For me, it’s also about storytelling — turning ideas into experiences and giving logic a narrative form. Whether it’s building a website, designing an interface, or writing content, I see coding as a creative medium just like art or writing. Coding as a Narrative Each function feels like a chapter with a defined purpose. Variables act like characters, carrying information through the story. Debugging introduces plot twists, forcing us to rethink the journey. The final program is the ending, bringing satisfaction when everything clicks. Where Storytelling Shapes Tech designing and editing on platforms like Canva, where visuals carried the story. Later, as I moved into web development, I discovered that coding too can be a powerful form of storytelling — one that combines creativity with interactivity. Why This Blend Matters Helps build user-focused experiences instead of plain functionality. Makes complex technical ideas easier to explain and teach. Brings creativity into problem-solving and design thinking. Conclusion connection. One connects machines with logic, while the other connects humans with meaning. Bringing them together is what makes digital experiences not just functional, but truly impactful.  ( 5 min )

Introduction Consensus algorithms are the backbone of distributed systems, enabling multiple nodes to agree on a single state despite failures or network issues. In technical interviews, questions about consensus algorithms like Raft or Paxos test your understanding of distributed systems’ reliability and coordination. These algorithms are critical for systems requiring strong consistency, such as distributed databases or leader election. This post explores consensus algorithms, focusing on Raft, and equips you to handle related interview questions with confidence. A consensus algorithm ensures that a group of nodes in a distributed system agrees on a single value or state, even if some nodes fail or messages are lost. This is crucial for maintaining consistency in systems like distribut…  ( 7 min )

Today I explored SQL Joins – one of the most important concepts in relational databases and also practiced with some coding problems on HackerRank. INNER JOIN → Returns only the matching rows from both tables. LEFT JOIN → Returns all rows from the left table + matched rows from the right table. RIGHT JOIN → Returns all rows from the right table + matched rows from the left table. FULL JOIN (or OUTER JOIN) → Returns all rows when there is a match in one of the tables. Among these, the most commonly used is the INNER JOIN. Let’s say we have two tables: movies movie_id movie_name 1 Ghajini 2 Singam 3 Kaakha Kaakha actors actor_id actor_name 1 Surya 2 Asin 3 Jyothika movie_actors movie_id actor_id 1 1 1 2 3 1 3 3 SELECT m.movie_name, a.actor_name FROM movies m INNER JOIN movie_actors ma ON m.movie_id = ma.movie_id INNER JOIN actors a ON ma.actor_id = a.actor_id; movie_name actor_name Ghajini Surya Ghajini Asin Kaakha Kaakha Surya Kaakha Kaakha Jyothika  ( 5 min )

My Story with ALX When I think about my ALX journey, one word comes to mind: transformation. I still remember the first time I signed up for ALX. At that moment, my goal was clear — I wanted to become a Virtual Assistant. I was eager to learn how to support busy professionals, manage schedules, handle communications, and create order in the middle of chaos. Those months as a VA learner shaped me more than I expected. I learned how to manage my time, stay accountable, and adapt to fast-paced environments. More importantly, I learned the value of community — how asking questions, helping others, and sharing experiences made the journey lighter and more rewarding. But something interesting happened along the way. The more I interacted with the ALX community, the more I became curious about what was possible beyond Virtual Assistance. That’s when I discovered Frontend Development. At first, the thought was intimidating. Me? Writing code? It felt far from my background. But ALX has a way of pushing you to dream bigger than your fears. And so, I took the leap. Now, I am walking a new path as part of the ALX Software Engineering program. Learning frontend development has been challenging, no doubt — there are moments when the code doesn’t work, when I feel stuck, and when giving up feels easier. But each time, I remind myself of the same lessons I learned as a VA: Ask for help. Stay consistent. See failure as feedback. Trust the process. In many ways, ALX has become more than just an education platform for me. It’s a community of growth. A place where you don’t just learn skills — you learn how to reinvent yourself. Today, I proudly say: This journey is still unfolding, but I know one thing for sure: with ALX, growth never stops. ALX_SE #ALX_FE #ALXJourney #ALX_Africa #GrowthMindset  ( 6 min )

There have been years of investigation into automated systems for everything from aircraft, weapon systems and unmanned drones to automobiles. Despite the millions, if not billions, of dollars invested and claims made by some electric vehicle manufactures, the day of fully-automated (aka self-driving) cars is a long way off. I would argue that handing over the responsibility for developing the systems on which our society (our civilisation) is so reliant, is an exceptionally dangerous strategy. Far more dangerous than streets full of driver-less vehicles, yet we seem to be determined to hand over this vital responsibility, according to some big businesses. Call them Software Developers or Software Engineers, it makes little difference if the AI hype is to be believed and all our jobs are a…  ( 7 min )

JavaScript isn’t just a programming language — it’s the reason our websites dance, pop, and feel alive ✨.

Have you ever wondered how your browser knows where to find www.dev.to? Imagine you want to send a letter to "www.dev.to" Root DNS Server = Central Postal Director This is like India’s central postal directory. It doesn’t know where dev.to lives, but it knows: "For .to domains, talk to the .to postal hub." Just like the central system knows: TLD Server = Regional Postal Hub (like .to Office) Authoritative DNS Server = Local Post Office "www.dev.to lives at 192.0.2.1".

The Most Important GPU Review of the Year (serious) Nvidia quietly rolled out the RTX 5050—destined for bargain-bin prebuilts everywhere—and gave reviewers almost zero lead time. Linus walks through 1080p and 1440p gaming tests, frame-generation and latency benchmarks, plus a healthy dose of real-world creator and AI workloads to see if this entry-level part can actually deliver. Spoiler: performance is underwhelming for gamers, and Nvidia’s marketing around “5050” only adds confusion. If you’re buying on price, it might make sense in ultra-cheap systems, but value-seekers and content creators will want to look elsewhere. Watch on YouTube  ( 5 min )

https://youtube.com/shorts/-SzPdzoeviA Even great diagrams can’t stop a project from going off track. Without structure, they’re just boxes. Still, many people believe architecture is only about making diagrams. The truth is, architecture is a repeatable practice that aligns people and delivers results. Diagrams are just one part of the work. Skip aligning objectives or defining scope, and you risk misaligned execution. That means blown budgets, missed deadlines, and frustrated teams. I’ve seen it happen — one project had a beautiful architecture map but still failed because critical dependencies were ignored and integration broke down. QTAM changes that. It gets everyone aligned fast, defines scope clearly, and produces deliverables that guide execution — cutting waste, avoiding delays, and driving better outcomes. 👉 Start here — https://qtam.morin.io/  ( 5 min )

Building fast, responsive React applications goes beyond writing functional code but also includes ensuring it performs optimally. Users expect pages to load instantly, scroll smoothly, and respond without lag, no matter how complex the app becomes. However, as React apps grow, bundle sizes increase, components re-render unnecessarily, and heavy lists slow down performance. The good news is that React provides multiple powerful optimization techniques that keep apps snappy while maintaining clean, modern code. The first step toward faster apps starts before the browser even runs your code: the size of the bundle itself. If your JavaScript bundle is bloated, performance issues appear before your app has a chance to load. That's where bundle optimization comes in. When you run a build, too…  ( 10 min )

Absolute Zero - What is Contextual Prompting? Let's ground ourselves. At its core, Contextual Prompting is the practice of providing an AI system with comprehensive background information, situational details, and relevant parameters before you even make your specific request. It's the difference between asking "Write an email" and giving your LLM a meticulously crafted brief that details the target audience, brand voice, campaign objectives, industry context, and desired outcomes. Modern LLMs, despite their intelligence, lack the inherent implicit knowledge and contextual awareness that humans take for granted. When I tell my colleague, "Summarize that meeting," they instantly know: Which meeting Who the summary is for What level of detail is needed Why they're summarizing it …based on …  ( 9 min )

The Composite Pattern belongs to the Structural category of design patterns. treat individual objects and groups of objects uniformly, by organizing them into a tree like hierarchy. Think about a Company Org Chart. An Employee can be a individual contributor. A Manager is also an employee, but they can have multiple employees reporting to them. Now, when their details are needed in order to distribute festive coupons, you don’t want different logic for developers and managers. You would just want to call the same method, and the right thing should happen. This is exactly what the Composite Pattern does in code.

Hi everyone 👋 I’m a full-stack web developer exploring WebAR with react-three-fiber (R3F) and would love some advice. My first project is to create an info wall for an exhibition, where users can hover over images to see more information. Later, I’d like to expand into more WebAR projects using the same tech stack, possibly integrating a headless CMS. From my research, the AR frameworks that seem best suited for my use case are: MindAR: seems solid for image tracking and works well with web apps. But it's not easy to integrate it into R3F. XR engines: ZappAR and 8th Wall – powerful, but expensive and I’d like to stay independent. Other options: AR.js: seems outdated and largely replaced by MindAR. react-three/xr: looks great for VR/HMD (Quest, etc.), but not focused on image tracking. My goal is to combine R3F with an image-tracking AR solution. I tried react-three-mind, but it didn’t work well for my project and is quite slow. I tried to integrate MindAR by myself but It's quite tricky, so I wanted to ask if there is a better solution? 👉 Has anyone here successfully built a React + R3F + AR app with image tracking or other ideas? Any pointers on tutorials, boilerplates, or best practices for React-based WebAR applications would be hugely appreciated 🙏😊 Thanks in advance!  ( 5 min )

TL;DR Step-Back Prompting asks an LLM to abstract a problem (produce a higher-level question or list of principles) before solving it. That two-stage approach — abstraction → reasoning — often yields more reliable answers for multi-step, knowledge-intensive tasks. Use it selectively: it costs extra tokens and latency, so benchmark and combine with retrieval when necessary. LLM: a token-predicting neural model (GPT-family, Claude, etc.). Token: a chunk of text used by the model. Prompt: the input/instructions you give the model. Step-Back Prompting: generate a step-back question or principle list first, then use that as grounding for the final answer. Note: Be precise — many real-world failures come from ambiguous prompts. Step-Back reduces ambiguity by forcing a model to surface the rele…  ( 11 min )

In the midst of the COVID-19 pandemic in March 2020, Sree Krishna Seelam, a visionary social entrepreneur, launched WeDidIT Foundation, a youth-centric non-profit based in Vijayawada, India. Despite starting with just seven volunteers operating from a residence within a containment zone, WeDidIT experienced explosive growth. This remarkable progress culminated in WeDidIT being honored with the Economic Times Award for Excellence in Social Entrepreneurship in 2021—a testament to its lasting impact . WeDidIT's ethos is deeply rooted in the belief that volunteering is not just an act of service but a path to personal transformation and leadership. During the pandemic lockdown, volunteers were encouraged to feed birds or animals at home, share photos on social media, and tag friends—creating a ripple effect of simple acts of kindness . Another notable initiative involved youth interviewing senior citizens (75+) in their circles, compiling responses and videos. These intergenerational exchanges fostered empathy, wisdom, and strengthened bonds between generations . Beyond localized projects, WeDidIT aligns with the United Nations Sustainable Development Goals—addressing issues such as No Poverty, Quality Education, Gender Equality, Clean Water and Sanitation, and Climate Action, among others . The foundation’s deeper mission is to cultivate volunteers into empathetic, purpose-driven leaders who carry the spirit of service beyond any single initiative . With the rallying cry, “To leave this planet a better place than it was before we arrived,” WeDidIT extends an open invitation to individuals of all walks of life—students, professionals, artists, and activists—to join a movement rooted not in perfection, but in shared humanity and purposeful action.  ( 6 min )

Building effective AI products isn't just about having access to powerful language models—it's about implementing the right design patterns that bridge the gap between AI capabilities and user needs. Whether you're developing a coding assistant, content generator, or analytical tool, these seven patterns will help you create AI experiences that users actually want to use. The Restating pattern addresses one of the most common friction points in AI interactions: miscommunication. Instead of immediately executing a request, the AI explicitly states what it understood from the user's input. Why it works: LLMs excel at filling gaps and correcting imprecise human input by leveraging conversational context. By restating before acting, you eliminate confusion and prevent costly mistakes.

Few foods have captured the hearts (and appetites) of people around the world quite like pepperoni. Known for its smoky, spicy, and savory flavor, pepperoni has become a staple ingredient in everything from pizzas to sandwiches, pastas, and party platters. Its bold taste and versatility make it a favorite for both casual meals and gourmet creations. Pepperoni traces its roots back to Italian-American cuisine, where it was crafted as a variation of traditional cured salamis. Over the years, it has grown into one of the most recognizable and widely used toppings in modern cooking—especially as the star of countless pizzas enjoyed worldwide. Unlike many other cured meats, pepperoni strikes a unique balance between heat and richness. Its seasoning blend, typically featuring paprika, garlic, and chili, gives it a distinctive flavor profile. This makes it not only delicious on its own, but also the perfect ingredient to complement cheese, bread, pasta, and even salads. While pizza may be its most famous use, pepperoni’s versatility stretches far beyond. It can be added to breakfast omelets, folded into sandwiches, tossed into pasta dishes, or paired with cheeses on a charcuterie board. Its ability to fit into so many different meals is part of what keeps it popular across cultures and generations. Pepperoni has earned its status as a timeless classic, offering a perfect mix of spice, flavor, and convenience. Whether you’re cooking a family dinner, preparing snacks for friends, or just craving a bold bite, pepperoni is always a winning choice.  ( 6 min )

Functions are the beating heart of JavaScript. They let us organize code, reuse logic, and build anything from small utilities to giant frameworks. But what really makes functions flexible are their parameters. These little guys decide how our functions receive input and how dynamic they can become.

I’m taking a gap year and my goal is to get a junior back-end position. I recently completed the CodeCademy Back-end Developer Course. To find out the standards for a back-end developer, I read stories and articles and what I commonly found were: Active GitHub profile (daily commits) Well-structured and documented programs (modular & uses Swagger Docs) Projects that are specific to my skill set (back-end would be APIs, server-side logic, databases, etc.) To implement this, I've planned out my year: Weekly mini-tasks to strengthen back-end skills Midyear project which compiles skills learned A capstone project Job prep for internships/junior position This is a fairly simple plan and I would love to hear input & feedback from the community about this plan. 👉 What other standards stuck with you that helped you get the job? Any stories, tips, or help is much appreciated.  ( 5 min )

In the previous lesson, we set up our Kotlin learning environment and completed our first program. This lesson will delve into the core of Kotlin's basic syntax—variables, data types, and operators. These form the foundation of any programming language, and mastering them will enable you to write functional code, laying the groundwork for learning concepts like functions and classes in subsequent lessons. Variables and constants are basic units for storing data. Kotlin makes a strict distinction between "mutability" and "immutability," which is an important difference from other languages like Python. In Kotlin, variables are declared using var and val, with the key difference being whether they can be reassigned: var (short for variable): Declares a mutable variable that can be reassign…  ( 14 min )

callback based - In callback based function we provide a callback function as an argument to a function like callbackBasedFn("Hello", (err, data) => {   if (err) {     throw new Error(err);   } else {     console.log(`data : ${data}😉`);   } }); Inside the callback we are getting err or data depending on the result of callbackBasedFn() callbackBasedFn can have internal implementation like below - function callbackBasedFn(data, cb) {   setTimeout(() => {     if (data === "error") {       cb("Something went wrong 😵‍💫", null);     }     cb(null, data);   }, 1000); } In this function we are doing some async operation that will result in data or err. So if we want to process the output of callbackBasedFn() we have to do it in callback fun provided to callbackBasedFn() itself like below -…  ( 8 min )

TL;DR: Large Language Models are powerful probabilistic predictors, but single-pass outputs can be fragile. Use Chain-of-Thought (CoT) to force step-by-step reasoning, Self-Consistency to sample many reasoning paths and vote, and Universal Self-Consistency (USC) to extend that voting to free-form outputs by letting an LLM pick the best response. Practical snippets and action cards included. Alright, let's architect some robust AI. You've got complex problems, and I've got the blueprints for turning Large Language Models (LLMs) into reliable, consistent problem-solvers. We're going to start at the bedrock, defining every single component, then ascend through Chain-of-Thought, Self-Consistency, and finally, Universal Self-Consistency, anchoring each layer with actionable, runnable patterns y…  ( 13 min )

Most consultants now use AI for content and strategy, but few apply the clarity and structure that drive results. You’ve probably seen it already. AI-generated pitch decks, polished landing pages, and neatly packaged strategy docs. What used to take hours now takes minutes. And yet, most of it feels empty. When everyone has access to the same tools and the same frameworks, more content doesn’t help. It just raises the noise level. The real difference comes from who thinks more clearly and builds systems that resonate. “Good Enough” Is the Starting Line, Not the Finish Sure, generative AI can produce decent strategy docs, clean content, and research summaries that look impressive on the surface. But this is everywhere now. Polished content is just the baseline, not a differentiator. Amy Be…  ( 7 min )

The VPS market is full of marketing claims — “premium,” “CPU-optimized,” “compute-optimized.” But what do you really get for your money? We wanted to find out. So we benchmarked 8 VPS types across 4 providers — AWS, Vultr, DigitalOcean, and Raff Technologies — all with the same baseline configuration: 4GB RAM, 2 vCPU, AlmaLinux 9.6. The results were surprising: price had almost zero correlation with performance. In fact, the cheapest VPS — Raff Technologies at $20/month — scored higher than AWS’s $74 c7a.large.

The childcare industry was valued at $60.4 billion in 2022 and continues to grow steadily. With more families where both parents work, the demand for flexible, reliable babysitting solutions has never been higher. Here are a few reasons why building a babysitter app makes sense today: Dual-income households are the norm. More parents are career-focused and willing to pay for flexible childcare options. On-demand services are booming. Just like food delivery or ride-hailing, parents want babysitters available on short notice. Trust through tech. AI matching, background checks, and secure payments make booking babysitters safer than ever. Sitters need visibility. Many caregivers only work part-time and need platforms to market their services easily. It’s more than babysitting. Pet sitting, tutoring, and even virtual babysitting are growing side-markets. Platforms like Care.com and UrbanSitter have already proven the model, but there’s still space to innovate — whether that’s in niche services, better security, or improved user experience. 👉 We’ve put together a full guide on building a babysitter app, covering features, business models, and challenges.

Theoretical Foundations of Digital Transformation Evolution of Agent-Based Systems Strategic Role of Intelligent Agents in Organizations Integration with Digital Infrastructures Human-Machine Collaboration Ethical and Governance Dimensions Impact Across Sectors The Role of Advanced Development Paradigms Future Directions of AI Agent Research Conclusion The phenomenon of digital transformation is inseparable from the evolution of intelligent computational agents. Through their capacity for autonomy, collaboration, and adaptability, agents reconfigure the structures of organizations, the design of infrastructures, and the dynamics of human-machine collaboration. The theoretical, ethical, and practical implications of this evolution reveal that agents are not merely instruments of efficiency but fundamental participants in socio-technical ecosystems. The future of digital transformation will be defined by the capacity to harness intelligent agents responsibly, integrating them into systems in ways that align with human values and institutional objectives. By advancing design paradigms such as Agentic Ai Development, Ai App Development, and Ai Development, societies can ensure that the transformative potential of intelligent agents is realized in a manner that is equitable, sustainable, and innovative. The progression of computational agents thus symbolizes more than technological advancement. It represents a redefinition of the relationship between humans and digital systems, a relationship that will continue to shape the structures of economy, governance, and culture in the era of intelligent transformation.  ( 10 min )

Brahma-JS: Ultra-Low Latency JS Runtime Powered by Rust Rust is amazing for speed, safety, and stability—but let’s be real: most JS/TS devs don’t want to wrangle the borrow checker, strict type system, and ownership rules just to build web APIs. That’s why I built Brahma-JS — an ultra-low latency runtime written in Rust on top of Tokio + Hyper, but plug-and-play with Node, Deno, and Bun. All heavy lifting (req.body, headers, query parsing, etc.) runs in Rust. Works directly inside your existing JS ecosystem (Node, Deno, Bun). Fire-and-forget, fully sync-style architecture. Lets you write type-safe, memory-safe, blazing-fast HTTP routes with the simplicity of JS. npm i brahma-firelight const { useBrahma, startServer, redirect } = require("brahma-firelight"); useBrahma((req) => { if (req.path === "/hi") { return { headers: { "Content-Type": "application/json" }, status: 200, body: JSON.stringify({ message: "Hello World from Brahma-JS!" }), }; } if (req.path === "/bye") { return redirect("https://example.com"); } return { status: 404, body: "Route not found", }; }); const port = process.env.PORT || 3000; const host = process.env.HOST || "0.0.0.0"; startServer(host, +port).then(() => { console.log(`🌀 Brahma-JS server running at http://${host}:${port}`); }); On a tiny AWS EC2 t2.micro, I hit: 33.2k req/s within 10s of load testing No proxy, no hacks — just raw Rust (Hyper + Tokio) under the hood Benchmarks August 2025 (That’s significantly faster than Express/Fastify on the same hardware.) 👉 GitHub: Shyam20001/rsjs Star ⭐ the repo if this excites you PRs welcome for early testers Drop issues with the features you’d want next Nobody needs to give up their ecosystem anymore.

"Faces don’t lie — but landmarks sometimes do." Hey there! In this post, I’ll share my journey of building a Face Landmark Detection pipeline using OpenCV DNN and Facemark LBF. The system takes a raw video as input, detects faces, extracts 68 facial landmarks, smooths them across frames, and finally outputs: an annotated video with landmarks and bounding boxes an optional CSV file with landmark coordinates for every frame The idea was simple: "Take a face → get the points." But to make it robust, I had to mix deep learning detection with classical landmarking and add a touch of signal processing. The project is split into modular components: detector.py → Loads and runs the DNN-based face detector (SSD ResNet) landmarks.py → Drawing utilities for the 68-point facial structure helpers.py → …  ( 6 min )

After some searching, I came across a course called AWS Mastery: 26 AWS Cloud Projects for Engineers & Architect on Udemy by Pravin Mishra. What I love about this course is that it isn't just theory, it focuses on practical, project-based learning. So I've decided to take on a personal challenge of working through each project without looking at the solutions while documenting my process here in this little world of mine. This way, I can build confidence whi…  ( 10 min )

Starting something new is always exciting—and a bit daunting! As a developer with experience in React and FastAPI, I recently decided to dive into the world of databases by learning SQL using PostgreSQL. My main goal is to bridge the gap in my backend skills and better understand how databases power the applications we build. With its open-source nature, strong community, and powerful features, PostgreSQL is a natural fit for those looking to expand their backend capabilities. It’s widely used in both small projects and large-scale production systems, making the skills transferable and future-proof. So far, I’ve covered the fundamentals: Installing PostgreSQL on my machine and setting up my first database Learning and practicing essential SQL commands like: CREATE TABLE INSERT SELECT Wri…  ( 6 min )

Artificial Intelligence (AI) and Machine Learning (ML) are revolutionizing mobile app development across the globe. According to Statista, by 2024, the global AI market size is expected to surpass $500 billion, with mobile apps being one of the primary industries adopting these technologies. In particular, the Android ecosystem, with its vast reach, is increasingly integrating AI and ML to enhance user experiences, improve functionality, and drive innovation. For Android app developers, AI and ML are no longer optional add-ons; they have become core components in creating smarter, more personalized, and more efficient applications. In this article, we explore how AI and ML are transforming Android app features, and how Android application development companies are leveraging these technolo…  ( 10 min )

If you work with multiple servers — some requiring .pem keypairs and others with password authentication — you know how quickly it becomes messy. Add in the fact that you might switch between Windows at home and macOS at work, and suddenly managing SSH connections can feel like juggling knives. In this article, I’ll show you how to organize your SSH access across both Windows and macOS using: OpenSSH (built-in on both OS) ~/.ssh/config (for managing profiles) Multiplexing (to speed up connections) tmux (to keep sessions alive even if your laptop disconnects) Let’s dive in 👇 macOS → Already installed, just open Terminal. Windows 10/11 → OpenSSH is included, but if missing: Settings → Apps → Optional Features → Add a Feature → OpenSSH Client Now you can run: ssh user@server-ip ~/.ss…  ( 7 min )

Large Language Models like GPT LLaMA, and Claude have seen a surge in popularity in the business world over the past few years. These advanced AI models process and produce text in ways that feel human, which makes them useful in a lot of business areas. Businesses are using LLM to automate customer support or to manage internal knowledge in a perfect way. But, when they rely on outdated LLM then they may face various issues like for more complex business demands, they may not give you proper results. That’s why, many businesses feel that they should update their LLMs to meet their business goals. When you make changes or adjust LLMs then it will affect their overall performance like how accurate they are, and how well they align with your business goals. But mistakes during the process c…  ( 9 min )

If you run last-mile in an apartment-dense metro, you’ve lived the pain: missed first attempts, drivers circling for parking, and rescue routes blowing up OT. The fix isn’t just “better maps.” It’s the boring, vital plumbing inside a route optimization app, clean geocodes, precise apartment waypoints, and an ETA model that reflects reality at curbside, not on a highway. This post breaks down how those pieces fit, and what operators should ask vendors before the next peak. At the core is geocoding. It turns an address into a latitude/longitude the router can trust. The difference between rooftop and centroid placement is the difference between a first-attempt POD and a second attempt tomorrow. For single-family stops, a centroid might be “close enough.” For towers and gated complexes, it’s…  ( 8 min )

In Silicon Valley's echo chambers, artificial intelligence has supposedly conquered coding. GitHub Copilot autocompletes your functions, ChatGPT debugs your algorithms, and Claude writes entire applications from scratch. Yet beneath the marketing fanfare and venture capital euphoria lies an uncomfortable truth: human programmers remain irreplaceable. While AI coding assistants excel at mundane tasks and pattern matching, they fundamentally lack the creative problem-solving, contextual understanding, and architectural thinking that define exceptional software development. The statistics surrounding AI coding tools paint an impressive picture. Microsoft reported that GitHub Copilot users complete tasks 55% faster than their unassisted counterparts—a figure that has become the rallying cry fo…  ( 19 min )

Most developers have seen this pattern before. At first, the team picks up tools like Zapier, Make, or HubSpot to move faster. They solve a few problems quickly, but then… everything gets messy. Data duplicated across CRMs, spreadsheets, and APIs. Integrations failing silently, forcing someone to “just fix it.” Compliance gaps that SaaS vendors won’t cover. Scaling limits where the workflow just can’t keep up. This is what we call the SaaS plateau. Off-the-shelf tools stop being accelerators and start becoming blockers. When you’re stuck patching integrations or debugging brittle APIs, it’s a signal. The problem isn’t you — it’s the architecture. A custom AI system changes the game: Single source of truth → no more wondering which system has the right data. Code-first integrations…  ( 7 min )

Hey everyone! 👋 I recently went through a classic "it works on my machine" scenario... except my machine was the Azure Cloud Shell, and it didn't work. Here’s a quick story of how I hit a Docker wall and used native Azure tools to successfully deploy my static fashion site to Azure Container Instances (ACI). Let's rewind. I was logged into the Azure Portal, staring at my resource group, ready to deploy my static site. My plan was simple: use the Azure Cloud Shell to run a quick docker build and docker push. I clicked that little >_ icon in the portal's header and got to work. Little did I know, I was about to hit a classic "gotcha" and find an even better solution. Here's how it went down.

It’s 2025. Immunefi and HackenProof might serve Web3 clients, but for us — the developers — the flow is still Web2. We’re long overdue to fix this. It’s time for something we own. ⚡ Introducing: The Developers Protocol This is our protocol. Just proof, payout, and progress. We call it: A zk-native, on-chain bounty system built by devs, for devs. 🧠 Why This Matters The current systems still gate the most important part of the process: us. We have to ask to submit. We have to wait to get paid. We often get deplatformed or ignored — even after saving entire protocols. Meanwhile, proof-of-exploit sits on our disk, ready. We can build that. Today. 🔄 Our Great Irony: We Forgot Ourselves Here’s the real kicker: We’ve designed zk-voting. But we forgot to fix the most critical PoC of all: our own. This is our own unsolved exploit. 🔧 What It Looks Like ✅ Submit a proof (zk-SNARK, signed hash, or PoC artifact) This is: Proof-of-Exploit Proof-of-Impact Proof-of-Authorship Proof-of-Code 🧑‍💻 And We’re the Right People To Build It It shouldn’t take long: zk circuits — we’ve done harder Solidity vaults — minimal Submission CLI — weekend job Decentralized bounty registry — a few commits away We are not just the security layer. And it’s time we start acting like it. 📣 Call to Arms If you’re a dev, this is your bounty call. 💥 Solidity / zk-devs — comment below Let’s get this spec on GitHub. 🏁 One Last Reminder: We forgot to secure ourselves. 💬 Comments Section Suggestions (For DEV.to engagement prompts at the bottom) “Would you use this instead of HackenProof/Immunefi?” “What zk format should we use for the first verifier?” “What’s the biggest flaw we must defend against in v1?” This is the one we’ve been waiting for.

Over the past few weeks, I’ve been experimenting with building a car classified script — something like a small-scale version of Autotrader or Cars.com, but with a focus on simplicity and adaptability. • Car Listings with Deep Filters • Backend: PHP + Codeignitor (for modularity) Search Speed on Large Data Filtering by make, model, location, and price killed performance after ~50k entries. Index tuning + caching helped, but I feel there’s a smarter approach. Image Uploads & Compression Car sellers love uploading 10+ high-res images. Handling auto-resize + CDN storage without killing speed was tricky. Dynamic Taxonomies Brands, Models, Variants, Years — keeping this flexible but not overly complex was harder than real estate listings. Payments for Featured Ads Simple integration with Stripe/PayPal works, but what’s the best way to keep it modular for regional gateways (PayU, Razorpay, etc.)? • How would you handle fast search + filtering at scale (Elasticsearch? Algolia? Something else?) I’m experimenting with a mobile app integration where listings update in real-time between the web + app. Also exploring a plugin system so small dealers can white-label their own version. Would love to hear from others who’ve tackled classified or marketplace apps: • What dev shortcuts saved you time? • What mistakes should I avoid scaling this?  ( 6 min )

If you’ve been building modern apps with React, Next.js, Angular, or Vue, chances are you’ve run into messy APIs, performance bottlenecks, or “too much data vs too little data” problems. That’s where Backend for Frontend (BFF) comes in. This article will explain what BFF is, why we need it, when to use it, real-world scenarios, common pitfalls, and examples — in the simplest way possible. Imagine you’re building an e-commerce app. Your mobile app needs a very compact API response (just product name, price, image). Your web app needs a detailed product view (reviews, specs, seller info). Your admin dashboard needs extra APIs (stock, margins, supplier details). If all of them talk directly to your core backend (say a bunch of microservices), you’ll end up with: Over-fetching data (getting mo…  ( 8 min )

If you’ve ever troubleshooted a slow internet connection, you’ve probably typed: ping google.com and watched those little reply times scroll by. It feels like a digital knock on someone’s door: “Hello? Are you there?” But here’s the twist, unlike most network tools, ping doesn’t use any port at all. When we think of network communication, ports are everywhere. Websites? They use TCP port 80(HTTP) or 443 (HTTPS). SSH? That’s usually port 22. DNS lookups? UDP port 53. But ping is different. It doesn’t ride on TCP or UDP, where ports live. Instead, it uses a separate protocol: ICMP (Internet Control Message Protocol). ICMP works one step lower in the networking stack — at the network layer (Layer 3) instead of the transport layer (Layer 4). And since ports only exist in Layer 4, ping never t…  ( 7 min )

Are you someone who works shifts and has trouble sleeping? Shift work sleep disorder is a common problem for people who work unusual hours, and it can make it hard to get enough rest at night. When your work hours keep changing, it can mess up your body's natural rhythm for sleep, which can leave you feeling sleepy or anxious during the day. So, what can you do to help with this problem and get the rest you need? Here are some tips to help you manage shift work sleep disorder and improve your sleep: Even if your work hours change, make an effort to have the same bedtime and wake-up time each day. Aim for at least 7 to 9 hours of sleep. This helps your body's internal clock stay on track and improves your sleep. Keep your bedroom dark, cool, and quiet. Use blackout curtains, a white noise machine, or earplugs to block out any distractions that might keep you from sleeping. If you still have trouble falling or staying asleep, you might want to try some Natural Sleep Supplements. Look for ones that have ingredients like melatonin, valerian root, or magnesium, which can help your body get ready for sleep. Avoid drinking coffee or eating big meals close to bedtime. Limit time spent on screens before sleep, and try relaxing activities like meditation or deep breathing to help you feel more calm and ready for rest. If you've tried these steps and are still struggling with sleep, it might be a good idea to see a doctor or sleep specialist. They can give you more personalized advice or suggest other treatments that could help. By following these tips, you can better manage shift work sleep disorder and feel more rested. It's important to take care of your sleep because it affects your energy, mood, and overall health. Don't wait too long to take steps that can help you feel better.  ( 6 min )

Agile terminology is something almost every team member comes across—whether in daily stand-ups, planning sessions, or project updates. Words like sprint, backlog, and retrospective have become part of everyday conversations. But here’s the thing: Agile terminology doesn’t stay the same. Just like the way teams work changes, so does the language they use. In 2025 and heading into 2026, we’re starting to see new terms appear in Agile conversations. Some of them stem from the rise of AI in Project Management, while others result from the shift toward focusing on outcomes rather than just outputs. Agile is also spreading far beyond software, which means the way people talk about it in marketing, HR, and operations is shaping new expressions.

Every developer has been there. You're staring at a 300-line function that somehow grew into a digital tumor over six months of "quick fixes." The code works, but it's unmaintainable. You know you need to refactor it, but the fear creeps in: what if you break something? What if the AI suggestion misses critical business logic? What if you lose control of your own codebase? I've found a way to use AI for refactoring that doesn't turn me into a passenger in my own code. It's not about blindly accepting AI suggestions or rejecting them entirely. It's about creating a partnership where I maintain architectural control while leveraging AI's pattern recognition abilities.

If you’ve enjoyed our last couple of tips about CouchDB document design then you’ll appreciate a tip that helps you query CouchDB quickly. This advice is relevant for all query mechanisms in CouchDB: Views, Mango Queries, and even Search. All query mechanisms in CouchDB use design docs to define which fields to use when querying your document. We call this the query definition. They look different for each of the mechanisms, but their function is the same in each case. When changing the query definition of a design document, CouchDB will re-index all documents in your database before it can respond to any queries for them. If you have a lot of documents in your database, going through all documents for re-indexing can take a while, minutes, hours, sometimes days. During application develop…  ( 6 min )

“What got you here won’t get you there.” That saying holds true in software development more than anywhere else. Imagine this: You’ve built a solid back-end system that works perfectly for your startup’s first 1,000 users. Everything is smooth… until suddenly you hit 10,000 users, then 100,000. Suddenly, performance drops, errors multiply, and adding new features feels like trying to fix an airplane mid-flight. This is the story of countless developers and companies who start with a monolithic architecture—and eventually discover the need for something more flexible, more scalable, and more maintainable.

Code is not just for machines — it’s for people. Future-you (or your teammates) will have to read, understand, and modify your code. That’s why clean code matters. It makes projects easier to maintain, scale, and debug. Here are 10 essential clean code principles to level up your development skills: Variables, functions, and classes should describe what they do. # Bad x = 10 def doStuff(): ... # Good max_retries = 10 def calculate_discount(): ... A function should do one thing, and do it well. Don’t scatter mysterious numbers/strings in code. Use constants instead: // Bad if (status === 404) { ... } // Good const NOT_FOUND = 404; if (status === NOT_FOUND) { ... } Use a consistent style guide. Python → Black / PEP8 JavaScript → Prettier / ESLint Formatting tools remove debates and keep code uniform. Why, Not What 💬 Your code should explain what is happening. Comments should explain why: # Bad i += 1 # increment i by 1 # Good i += 1 # move to the next index for processing If you copy-paste code, that’s a red flag. Extract it into a function or utility. Handle errors early and clearly. Don’t let issues hide deep in your program. Tests = clean code’s safety net. They ensure changes don’t break existing functionality. Avoid over-engineering. If your solution is complicated, ask: “Is there a simpler way?” Code ages. As requirements change, revisit and clean it up. Small, frequent refactors are better than giant rewrites. Clean code isn’t just about style — it’s about maintainability, readability, and professionalism. The cleaner your code, the easier it is for others (and your future self) to work with it. 💬 Which clean code principle do you struggle with the most? Or do you have your own golden rule?

(Automated) testing is probably one of the most overlooked technique in the programming world. Traditionally in the software development industry we had a clear separation between "programmers" or "coders" or "software engineers" on one hand and "qa people" or "testers" on the other hand. The latter would do the manual testing, the Quality Assurance of the product. Traditionally the company and thus the programmers relied on the QA people to find the bugs and to ensure high quality. This approach was never really good, but today it totally breaks down for a variety of reasons in a number of cases.

Running AI models in the browser used to be a pipe dream. Neural networks required powerful GPUs, gigabytes of memory, and server-side processing. But what if I told you we're now running a complete text-to-speech AI model entirely in your browser, with no server communication whatsoever? This is the technical story of how we built our Text to Speech tool using KittenTTS, ONNX Runtime, and WebAssembly—creating a privacy-first, unlimited AI voice synthesis system that runs completely client-side. The Technical Challenge Traditional text-to-speech systems rely on server-side processing for good reason: Model size: Neural TTS models can be hundreds of megabytes Computational complexity: Voice synthesis requires intensive matrix operations Memory usage: Audio generation consumes significant RA…  ( 11 min )

Introduction When you install software on Linux, you don’t always download it from a website like on Windows or macOS. Instead, Linux uses package managers. RPM and YUM. They work together but solve different problems. RPM (Red Hat Package Manager) is the low-level tool for handling software packages. A package is usually a .rpm file that contains the software and metadata about it (version, dependencies, etc.). RPM can install, remove, or query a package directly. rpm -ivh mypackage.rpm # installs a package rpm -e mypackage # removes a package ⚠️ Problem: RPM does not automatically resolve dependencies. If software A needs software B, you must install B yourself. YUM (Yellowdog Updater, Modified) is a higher-level tool that builds on RPM. It automatically resolves dependencie…  ( 6 min )

Hello again to all the people who are still here! For this week, on my 2nd game/mini project, I created the usual stuff, game.cpp, .h, main.cpp and added the ability to close the window with the toolbar and the escape button which I'll always think is a neat touch I also learned to create a player class! It was a bit complicated to integrate it but in the end I could get it to work and could see my player in the game window when I ran the app! I'm so excited for what's next, I hope I could get to do more though as I haven't been doing well these past a couple of weeks Anyhow, stay safe and see you all again soon! Maybe even sooner than you might think cause one week goes by really fast I'm always surprised.  ( 5 min )

Introduction "The Art of Programming is the Art of Organizing Complexity" - Edsger Dijkstra I'm not a dogma guy, so don't expect me to talk about "ports and adapters" or "clean architecture" here. Instead, I want to share a mindset that has helped me and many others build better software. What follows is not just about software, but about how to think like a great developer. Let's picture the following: you hand a group of developers a huge pile of LEGO bricks and ask them to build a rocket. Some will sketch blueprints, carefully laying out every component before placing a single brick. Others will immediately start building, creating elaborate structures, only to watch them collapse under their own complexity. But a rare few - the best developers I've worked with - will do something dif…  ( 9 min )

Understanding the Core Technologies When building AI agents, you'll face a critical decision: should you use Model Context Protocol (MCP) or traditional APIs? This choice can dramatically impact your agent's capabilities, performance, and development timeline. MCP serves as a universal translator between AI systems and external services. It creates a natural language bridge that enables LLMs to independently discover and utilize tools based on the situation at hand. The key advantage? Autonomous discovery and usage without explicit programming. Meanwhile, traditional APIs (REST, GraphQL, etc.) continue to serve as the foundation of software integration. When building with APIs, you're essentially pre-determining what your agent can do at design time through hard-coded calls or function i…  ( 12 min )

Web Components & Custom Elements: Building Reusable UI with Native Power Introduction In the ever-evolving landscape of web development, component-based architecture has emerged as a cornerstone for building complex and maintainable user interfaces. While frameworks like React, Angular, and Vue.js offer powerful component models, the web platform itself provides a native solution: Web Components. Web Components are a set of web platform APIs that allow developers to create reusable, encapsulated, and interoperable custom HTML elements. This article delves into the world of Web Components, focusing specifically on Custom Elements, one of the core specifications that enable their creation. We'll explore the prerequisites, advantages, disadvantages, features, and provide practical examples …  ( 9 min )

This article focuses on optimization. The previous article introduced a complete compilation script that successfully builds the WebAssembly version of GDAL. However, the compilation results are not suitable for production environments because: Excessive file sizes: Core wasm file (27MB), glue code (272KB), data file (11MB) Redundant glue code: Contains Node.js and bash environment code, impossible to tree-shake Debug info in production: Debug information is unnecessary in production environments File size is the most critical issue—total artifacts exceed 38MB, which is unacceptable for any web application. Additionally, the Makefile contains misconfigurations. Since emsdk silently ignores unsupported compilation options during build, these errors don't halt compilation. This article will…  ( 8 min )

Hey everyone – I'm a dev who got hit hard by subscription fatigue. You know the feeling: every cool AI tool wants a monthly fee, and before you know it, you're juggling a dozen paid plans. I reached a point where I thought, there has to be a free, open-source way to do this stuff. Good news – there usually is! Open-source AI tools are not just about saving money; they give you control over your data, the ability to self-host, and often a whole community adding new features. In this post, I'll share seven open-source tools that have replaced big chunks of my paid stack. These tools boost productivity, automate tedious workflows, and just make life easier – all without the recurring bills. Manus is a powerful multi-agent AI tool, but it's proprietary and pricey: it charges $39 per month f…  ( 9 min )

Graphics programming in Linux during the 1990s was fragmented, with developers forced to choose between virtual consoles, svgalib, and the X Window System. Each subsystem came with its own interfaces, constraints, and quirks. This created challenges for developers who wanted to write applications that worked reliably across different environments. The General Graphics Interface (GGI) project was introduced to address these challenges by offering a more portable and secure approach to graphics handling. The project’s vision centered on portability through a flexible API that could reduce complexity for developers. By simplifying API integration across backends and platforms, GGI aimed to eliminate the need for redundant code in graphics applications while also making them easier to adapt an…  ( 7 min )

1. What is Algorithm Complexity? Algorithm = step-by-step procedure to solve a problem. Complexity = how much time or memory it needs as input size grows. We measure this using Big-O notation. 2. Why Big-O Notation? It describes the growth rate, not the exact time. Helps compare algorithms (fast vs slow) independent of hardware. Example: One algorithm takes 1 second for 1000 inputs, another takes 10 seconds — Big-O tells us how this scales when inputs grow to 1 million. 🔹 O(1) → Constant time Same time, no matter the input size. Example: access arr[5], simple formula like n(n+1)/2. 🔹 O(log n) → Logarithmic time Input size shrinks in half each step. Example: Binary Search in a sorted array. 🔹 O(n) → Linear time One loop over all n items. Example: Find the max element in an array. 🔹 O(n log n) → Linearithmic time Appears in efficient sorting algorithms. Example: Merge Sort, Quick Sort. 🔹 O(n²) → Quadratic time Double loop → compare all pairs. Example: Bubble Sort, checking all pairs in a matrix. 🔹 O(2ⁿ) → Exponential time Doubles work for each extra input. Example: Recursive Fibonacci, brute force subsets. 🔹 O(n!) → Factorial time Explodes very fast → all permutations. Example: Traveling Salesman (brute force). Formula: Already solved shortcut, runs in O(1). Example: Sum of first n numbers = n(n+1)/2. Algorithm: Step-by-step method to compute the answer. Example: Loop through numbers and add one by one = O(n). ✅ TL;DR: Big-O tells us how fast/slow an algorithm grows with input size. Formulas are direct (O(1)), algorithms can vary (O(n), O(n log n), etc). Choosing the right algorithm = huge performance difference in real-world apps.

It’s not always a provider issue. In most cases, it comes down to how Linux allocates resources and how system tools report them. Here’s why: Memory: The kernel + firmware reserve a slice. Tools also report in MiB/GiB, not MB/GB. Disk: Some space goes to system partitions + unit conversions. In short: what you see is expected. Nothing “missing” - just Linux doing its thing.

The Excel Sheet That Broke Ankita Picture this scenario that's painfully common across Indian businesses: It's month-end. Ankita, CFO of a growing EdTech startup, stares at her screen showing 1,847 bank transactions. Her team needs to match each one to a student account. Some paid via NEFT with cryptic references like "FEES" or just their child's nickname. Others used IMPS with transaction IDs that don't match any invoice. "We're an education company," she tells her CEO during yet another late-night reconciliation session. "But I spend 60% of my time being a detective, matching payments to students." This hypothetical scenario plays out in thousands of Indian businesses daily. The irony? In an era of instant payments, businesses still reconcile like it's 1995.

When people hear that I worked on distributed storage at Meta, they assume I must have taken the intensely technical path: writing C++ from day one, digging deep into operating systems, and building algorithms from scratch in college. JavaScript? Web development is one of the best places to start your career as a software engineer, even if your goal is to work on systems. I didn't fully understand memory models or system calls when I started programming. But I did understand one thing: I wanted to build something real. Even building a login form introduces you to concepts like authentication, state management, HTTP protocols, layered architecture, and interfacing with databases. These are not minor ideas - they're foundational. I promise, you'll be far better prepared than someone who tries to start at the deepest end of the pool and is overwhelmed by abstraction. Every complex system you admire has started somewhere small. Google started with a basic search box. Facebook started as a student directory. Even the most advanced distributed systems begin as simple requests, moving through a stack of layers, each doing its job. Start with web development. Not because it's easy. But because it's one of the most effective ways to learn how computers work, and how people use them. And if you stick with it, you'll be surprised at how far it takes you. I certainly was.  ( 8 min )

Background – How I Landed the Task When I first joined Ozone, one of my first assignments was migrating node services to Supervisord. Soon after that, my CTO dropped a bigger challenge on my plate—something more open-ended: "Why don't you build us a tool to validate the configs we generate?" Now, here’s the tricky part—each client has their own environment, which means their generated configuration files look different. Manually validating them is not very practical. What worked for one client would completely break for another. That’s when we needed custom tooling, tailored for this validation. And before we dive in—don’t worry, this isn’t going to be a deep dive into technical jargon. My goal here is to share the approach I took to build it, the thinking process, and a few lessons (and…  ( 7 min )

It feels so great when you buy a shirt, and while paying you find out another one is free. We all love free stuff, don’t we? Now, when you’re just starting to build your website, do you really want to pay for hosting before you’ve even earned a single dollar from it? I know even wealthy people like you wouldn’t say no to free hosting 😂. Luckily, there are several cloud platforms with free tiers. One of the best is Netlify. Netlify is a platform to build, deploy, and manage modern web apps—and yes, you can deploy your React app there without paying a dime. In this tutorial, I’ll show you how to do it. Don’t worry, I won’t be customizing the React app—we’ll stick with the boring default landing page. Why? Because I’m lazy 😪. Steps: Open your workspace in Visual Studio Code. Open the terminal and create a new React App, using the command npx create-react-app app-name. Go to your app folder and run the command npm start. React's default landing page should show up at http://localhost:3000. Push your code to GitHub. Login to Netlify using Github account. Enter Signup Questions. From the List of Git providers select GitHub. Select and authorise Netlify to access your repository. Start deploying your React project. Below command is used to build your project Once your build is successful your website will be published. If you haven't given any name to your website Netlify will generate a random name. You can click on the link and open your website. You can change the name of your website by navigating to Project Configuration-> Change Project Name. Now click on your website link and share your website. Boom! Your React app is online. And you didn’t even have to touch a server, configure domains, or sell your kidney for hosting fees. Netlify did all the heavy lifting while you sat back lazy (respect ✌️).  ( 6 min )

An enumerated field has only several values. The format of filtering condition specified on an enumerated field (f) can be f =v1 or f=v2 or…, f !=v1 and f !=v2 and…, in or not in. The database compares f with n values. When the data table is large, there is a great number of comparisons, resulting in low performance. The larger the value of n, the lower the performance. If no comparisons are involved for performing the filtering operation, the performance will become much higher. esProc SPL offers alignment sequence mechanism to achieve that target. Take the orders table to look at how to use the alignment sequence. First, determine the range of values in an enumerated filed. customer_id field has a corresponding dimension table and its value range can be determined. Neither employee_id fi…  ( 8 min )

When you submit a PR, it includes a wrong previous commit. How to remove these commits? If you are developing on another branch, switch to that branch. If you are developing on main, you can skip this step. git checkout your-branch In Github, view the current PR and check how many commits it includes. Replace n in the following command with the number of commits and execute it (if you have synchronized the fork, there will be new commits in Github, but they will not be shown in VS Code, so the rebase result may be earlier than the first commit of the PR): git rebase -i HEAD~n In the command line, you will see something like the following text: pick 888a17a add pnpm setting in windows (#15) pick 472jkda add pnpm setting in windows pick 472bd9c add switch butoon pick 0369726 add dark theme change …… The commit with the Github PR number will be shown with a hash symbol and the PR number. For example, if I want to remove the second commit, I will change pick to drop. To force push the changes, use the following command: git push origin HEAD:your-branch --force This will force push the changes to Github, and the PR commits will be updated.  ( 5 min )

API versioning is the method of managing different versions of an API over time. As APIs evolve, new features are added, existing structures are modified, or removed. This can cause applications that use the API to break. API versioning allows us to make these changes in a controlled way, ensuring that existing users can continue to work without being affected. Why is it Important? 🚀 Maintains backward compatibility 🚀 Allows new versions to be released without affecting users of older versions 🚀 Enables large changes to be rolled out step by step 🚀 Lets API consumers choose which version they want to use 🚀 Simplifies the development and maintenance process 🚀 Provides the ability to fix bugs or shortcomings in new versions ✅ In short, API versioning ensures that an API remains safe, compatible, and sustainable for both developers and users.  ( 5 min )

Java interviews often include tricky questions—not to confuse you, but to test how deeply you understand the language. The good news? With the right analogies, even the toughest questions become easier to remember and explain. 🔹 Question 1: Can We Override a static Method? ❌ No, static methods cannot be overridden (they belong to the class, not the object). Analogy: 🔹 Question 2: Why is String Immutable in Java? Answer: For security, caching, and performance reasons. Analogy: 🔹 Question 3: What Happens If You Don’t Override hashCode() and equals()? If you put objects in a HashSet or HashMap, unexpected behavior occurs—duplicates may not be recognized. Analogy: 🔹 Question 4: Difference Between == and .equals() == → Checks reference (are they the same object in memory?). .equals() → Checks value/content.

Have you ever scrolled through Twitter/LinkedIn and seen indie hackers bragging about their SaaS hitting $10k MRR and thought: “That’s cool, but I’m not building the next Stripe. So why should I bother?” Here’s the thing: building even a tiny SaaS app — whether it makes $1 or $0 — can teach you skills that tutorials and side projects simply can’t. In this post, we’ll explore why developers should build mini SaaS projects, what you’ll learn, and how to get started (without burning out). Most dev projects are to-do apps or clones. Nothing wrong with that, but they usually stop at: CRUD operations Local testing Maybe a login screen A SaaS project forces you to think bigger, because you’ll need things like: Authentication & security → handling real user accounts Payments & sub…  ( 7 min )

🏗️ Java System Design With Code: Building Scalable Systems Made Simple When interviewers ask you system design questions in Java, they’re not just testing syntax—they want to know if you can think like an architect. But don’t worry: with the right patterns, examples, and mindset, system design in Java becomes much less intimidating. 🔹 Why System Design Matters Companies like Amazon, Google, and Netflix want developers who can design systems that scale. Writing code is one thing—but designing how components interact is the real test. Good design = performance, reliability, and maintainability. 🔹 Key Principles Scalability – Can the system handle 1 user… or 1 million? Fault Tolerance – If part of the system fails, does the rest keep running? Readability – Clean, modular code that others can understand. Extensibility – Easy to add new features later. 🔹 Example: Designing a Simple URL Shortener Imagine building a Java-based URL shortener (like Bitly). Requirement: Convert long URLs into short ones. Approach: Use Hashing or Base62 encoding for unique IDs. Store mapping in a database (MySQL/NoSQL). Implement caching (e.g., Redis) for faster reads. Java Code Snippet import java.util.HashMap; public class UrlShortener { http://short.ly/"; public String shorten(String longUrl) { String key = Integer.toHexString(longUrl.hashCode()); map.put(key, longUrl); return BASE + key; } public String expand(String shortUrl) { String key = shortUrl.replace(BASE, ""); return map.getOrDefault(key, "URL not found"); } } 🔹 Patterns to Know for Interviews Singleton → For global resources like DB connections. Factory → For object creation flexibility. Observer → For event-driven systems. Builder → For constructing complex objects step by step. 🔹 Full System Design Guide I’ve written a detailed breakdown of Java system design with examples and code snippets here 👉 🔹 Final Thoughts System design is where Java knowledge meets real-world application. ✍️ Originally published via AnalogyAndMe.com  ( 6 min )

Preparing for Java interviews can feel overwhelming. You study OOP, memory management, exceptions, multithreading… but when you sit in front of the interviewer, nerves kick in. The secret? 👉 Analogies. 🔹 OOP Concepts: The Restaurant Analogy Class → Think of it like a menu. It defines what’s available. Object → An actual dish you order from the menu. Inheritance → A specialty restaurant that takes a base menu and adds its own flavor. Polymorphism → The same “dish” name, but prepared differently (spicy, mild, vegan). 🔹 Garbage Collection: The Janitor Analogy Garbage Collection in Java is like a janitor in a library. Readers (your program) borrow books (objects). When no one needs a book anymore, the janitor quietly clears it away. You don’t control when it happens—but you trust it to keep the library clean. 🔹 Multithreading: The Airport Analogy Imagine an airport with multiple runways. Each plane is a thread. The air traffic controller (CPU scheduler) decides who takes off and when. More runways = more concurrency, but too many planes at once causes chaos. 🔹 Why Analogies Work in Interviews They show you truly understand the concept (not just memorized definitions). They make your answers stand out compared to robotic textbook replies. Interviewers love candidates who can explain complex topics simply. 🔹 Full List of Analogies I’ve compiled a detailed guide of Java interview questions explained with analogies here 👉 🔹 Final Thoughts Whether it’s OOP, threads, or garbage collection, analogies stick. ✍️ Originally published via AnalogyAndMe.com  ( 6 min )

When it comes to Java, few things spark more debate in developer interviews than “Which version do you prefer—Java 8 or Java 17?” Both are milestone releases, but their features, performance, and interview relevance differ in key ways. Let’s break it down. 🔹 Java 8 – The Old Reliable Released in 2014, Java 8 revolutionized coding style with: Lambdas & Streams → Functional programming in Java Optional Class → Handling nulls more gracefully Date & Time API (java.time) → Finally, a modern replacement for Date For many companies, Java 8 is still in production, so interviews often test candidates on these fundamentals. 🔹 Java 17 – The Modern Powerhouse Fast forward to 2021, and we get Java 17, a long-term support (LTS) release packed with improvements: Sealed Classes → Better inheritance control Pattern Matching → Cleaner and safer type checks Text Blocks → Simplified multi-line strings New Garbage Collectors → ZGC & G1 for performance boosts Security & Performance → Stronger out of the box 🔹 Which One Should You Learn? If you’re preparing for interviews → Master Java 8 + Java 17 differences. Interviewers love to test migration knowledge. If you’re working on modern projects → Go for Java 17. It’s faster, more secure, and future-proof. 🔹 Side-by-Side Quick View Feature Java 8 Java 17 Lambdas & Streams ✅ Introduced ✅ Still relevant 🔹 Read the Full Comparison I’ve written a detailed, interview-focused breakdown of Java 8 vs Java 17 here 👉 🔹 Final Thoughts Java 8 → Still important, especially in interviews. Java 17 → Future-ready, packed with features, and here to stay. If you’re serious about Java interviews or upgrading your skills, understanding both is non-negotiable. ✍️ Originally published via AnalogyAndMe.com  ( 6 min )

Initially I struggled to find the right approach to the problem. I used 3 pointers thought it would save the performance cases. But I was wrong there, this is a two pointer problem after sorting. Approach: for an index i, take j and k such that, arr[i] + arr[j] +arr[k] equals 0. Handle duplicates for i,j,k by comparing current to next index elements Try all combinations using while loop inside a for loop Time Complexity: O(nlogn) + O(n*m) where m is elements from next to last element.

We've all seen the headlines. "AI Will Replace 300 Million Jobs!" "Developers Obsolete by 2030!" "The Robot Apocalypse is Here!" But here's the thing: after working with AI tools daily and watching this transformation unfold in real-time, I've realized we're asking the wrong question. Remember when calculators were going to make mathematicians obsolete? Or when IDEs would eliminate the need for programmers because "anyone could code"? Let's be honest about what current AI can and can't do: What AI excels at: Generating boilerplate code faster than you can type What AI struggles with: Understanding business context and stakeholder needs AI is incredibly powerful, but it's still a tool. A very sophisticated tool, but a tool nonetheless. Here's where it gets interesting. While AI won't replac…  ( 8 min )

The Internet of Things (IoT) connects everyday devices such as sensors, smart appliances, wearables, and industrial machines to the internet, enabling seamless communication and automation. While this interconnectivity provides convenience, efficiency, and innovation, it also raises significant concerns about user data privacy. IoT devices constantly collect vast amounts of sensitive information, including health data, location details, personal habits, and even financial transactions. Unlike traditional systems, IoT devices often have limited computing power and security capabilities, making them more vulnerable to cyberattacks. Additionally, the fragmented ecosystem of IoT where multiple vendors and platforms operate creates interoperability issues that can expose data during transmission. In many cases, users are unaware of how much data is collected, how long it is stored, and who has access to it. Weak encryption, inadequate authentication, and insufficient regulations further amplify the risks. A single compromised IoT device can act as a gateway, exposing entire networks to malicious intrusions. Thus, ensuring user data privacy in IoT requires stronger encryption standards, transparent policies, and secure-by-design approaches. Anyone seeking deeper knowledge in this domain can benefit from structured learning, for example through an IoT certification course.  ( 5 min )

Claude knows about your Stripe webhooks, your database schema, that weird edge case with European VAT. Life is good. Then your PM pings you. Production bug. Critical. Drop everything. git stash git checkout main git checkout -b hotfix/critical-bug-fix You open Claude Code and... it's still talking about Stripe webhooks.

Decoding the Mystery: Bias-Variance Trade-off in Machine Learning Imagine you're trying to hit a bullseye with darts. Sometimes you miss wildly (high variance), other times you consistently hit the same spot, but far from the center (high bias). The perfect throw lands consistently close to the bullseye – a balance between bias and variance. This analogy perfectly captures the essence of the bias-variance trade-off in machine learning. It's a fundamental concept that dictates the accuracy and generalizability of our models, and understanding it is crucial for building effective and reliable machine learning systems. In machine learning, the goal is to build models that accurately predict unseen data. However, models are prone to two types of errors: Bias: This refers to the error introdu…  ( 9 min )

Introduction: Why Memory Allocation Matters in Go Hey Gophers! If you’re building high-performance apps in Go—think microservices, API gateways, or real-time data pipelines—memory allocation can make or break your system. Frequent allocations of small objects (like structs for JSON parsing) can hammer your garbage collector (GC), while large objects (like buffers for file uploads) can spike memory usage and crash your app with out-of-memory (OOM) errors. Sound familiar? Imagine your app as a busy warehouse: small objects are like tiny packages cluttering shelves, causing fragmentation, while large objects are bulky crates eating up space. Go’s memory allocator, inspired by tcmalloc, is built for speed and concurrency, but without the right strategies, you’re leaving performance on the ta…  ( 14 min )
